Full textCyclic ethers and lactones are important compounds in flavour and fragrance chemistry. The scope of this work was focused on the elaboration of a new catalytic system promoting cycloisomérisation of unsaturated alcohols and carboxylic acids to cyclic ethers and lactones, respectively. The use of metallic triflates (Mn+(OTf)n) as Lewis superacids led us to elaborate a new catalytic system involving aluminium or tin triflate (5% molar) in nitromethane. This system was applied to the synthesis of interesting compounds such as spiroethers, spirodilactones as well as cyclic thioethers and thilolactones. An alternative synthesis of rose oxide and Doremox was proposed. The use of chiral ligands to promote asymmetric cyclisations was examined and this study continues in our laboratory. A theoretical study associated to NMR analysis led to some mechanistic insights with proposed reaction mechanism

Full textIn the last past years, an increasing awareness of the hazards linked to the use of solvents has strengthened the regulation and forced to optimize their use. This evolution entailed an increasing interest for bio-solvents, i.e. solvents from renewable materials and with good health and environmental properties. In this context, isosorbide, a diol obtained by the double deshydratation of sorbitol, might be valuable synthon for the design of a wide range of molecules and polymers. The short isosorbide diethers (_ 5 carbones per alkyl chain), as they are biosourced and liquid at ambient temperature, are potentialy promising solvents, that is why they have been studied. The monomethyl isosorbides (-endo et -exo forms) have also been evaluated, as they are the main impurities of the commercial dimethyl isosorbide (DMI), the most promising compound of this solvents family. The physicochemical, functional and applicative properties that are necessary to the characterization and the use of new solvents have been assessed : the thermo-physical properties (vapor pressure, vaporization enthalpy), the optical and electrical properties (refractive index, dielectric constant, dipole moment), the functional properties (viscosity, partition coefficient, Kamlet et Taft solvatochromic parameters) have been measured. The environmental, health and safety profile of DMI has been determined and compared to common solvents, allowing the evaluation of its "greenness". As DMI is fully miscible with water, its physicochemical properties in aqueous solutions have been studied as well, and have enlightened a self-aggregation of DMI within a large concentration range.A solvent design process has then been developped in order to estimate the potential use of these new solvents. A novel approach for the classification of solvents has been proposed, based solely on the solvent molecular structure and relying on the "COnductor-like Screening MOdel for Real Solvents" (COSMO-RS) in which solvents are considered in their liquid state. This approach has allowed the classification of 152 solvents into 10 classes without requiring the knowledge of any experimental data. The approach has been applied to DMI and allowed to find some potential applications that have been evaluated, among which the use of DMI as fluxing agent for bitumen composition, coalescing agent for water-borne paints, solvent for paint strippers, solvent for ink removal, or coupling agent for the formulation of liquid detergents

Full textThis work is concerned with two topics: 1) the behavior of Ɣ and Ƹ-acetylenic carbonyl compounds (β-diketones, β-ketoesters and monoketones) towards some catalysts. The couple mercury chloride/chlorhydric acid has shown the greatest of efficiency and cyclises, at 35°, the β-dicarbonyl compounds in nearly quantitative yields. When these carbonyl compounds and the mercury chloride are adsorbed on solid supports, the cyclisation occurs generally faster and with better yields than in solution. 2) the intramolecular C-vinylation of acetylenic trialkylsilyl enol ethers of Ɣ, ʆ, Ƹ and [symbol] -acetylenic monoketones and Ƹ-acetylenic aldehydes, induced by mercury chloride, which has lead in high yields, via a cyclicoxovinylmercurial, to a) l-acetyl 2-alkylidenecyclopentanes (or cyclohexanes), β-methylene-spiranones, bicycloalkanones and propellanones, by hydrolysis ; b) fonctionalised compounds by stereospecific electrophilic substitution of the mercury atom. This new reaction is regiospecific (the cyclisation occurs between the enol carbon a tom and the non-terminal acetylenic carbon atom) and stereospecific (the addition on the triple bond is always cis)

Full textThe complexion of LiAlH4 with several crown-ethers (CE) has been studied in benzene solutions. Six CE were tested : 12-C-4, 15-C-5, benzo 15-C-5, 18-C6, dicyclohexano 18-C-6 and dibenzo 18-C-6. In allcases except for B 15-C-5 an equi-molar complex EC/LiAIH4 (or 1/1) is formed. Chemical species in solution were characterized by N. M. R. , I. R. Spectroscopy and conductimetry. A special attention was paid to the two isomers syn and anti of DC 18-C-6. The (AIH4)- anion is thus described for the first time as a dissolved species in a non-polar solvent. A drastic "nipper effect" against the cation-anion bond in LiAlH4 is observed in the case of the syn isomer of DC 18-C-6. Measurements of electrical conductivities in benzene confirm these results. EC/LiAIH4 complexes have been obtained in the solid state by precipitation with hexane from their solutions in benzene. D. S. C. Analysis have been performed in order to characterize the thermal behaviour. The existence of a glassy state is revealed in most cases

Full textThe first part of this work concerns the synthesis of macrocyclic Z-skipped polyolefines. A new synthetic approach toward the all-Z-cyclododeca-1,4,7,10-tetraene (CDT) was achieved, via a dimerisation of ylids in presence of oxygen, in five steps with an excellent Z selectivity and, in 28 % overall yield. This methodology has been applied on others cyclic polyolefines. For example, the all-Z-cycloocta-1,4,7,10,13,16-hexaene was prepared in 10 % overall yield over nine steps. The second part was devoted to the reactivity of CDT. The metathesis reaction of CDT conducted over ruthenium or molybdenum carbene catalysts leads exclusively to the cyclohexadiene in quantitative yield. In the presence of terminal olefin, no cross metathesis reaction product of CDT were observed. The polyepoxidation of CDT with m-CPBA or DMDO yielded tetraepoxide with an unexpected selectivity which was determinated by both NMR and X-Ray investigations. Furthermore, when the reaction was conducted sequentially, each epoxidation reactions occured with high regio and stereoselectivity. In order to understand the origins of the observed selectivities, a theorical study using semi-empirical calculation AMI has been carried out. Finally, the reactivity of the polyepoxides of CDT was investigated under Lewis acid activation. Reaction of CDT-tetraepoxide with HC1, HBr or EtOH in the presence of borontrifluoride-etherate lead to polycyclic ethers having an oxabicyclo[5. 5. 1] core which has never been described. Finally, in the last part, CDT was used as ligand of silver cation. Two different X-Ray structures were obtained depending of the counter-ion of the metal

Full textThis work deals with the elaboration of azlactone-functionalized insoluble supports by suspension polymerization. The methodology of designs of experiments (DoE) enables to control each parameter of this system. The azlactone functionality was also included into polyHIPE (High Internal Phase Emulsion). These supports were then used is solid-phase organic synthesis. [4+2] and [3+2] heterocycloadditions were performed with a supported vinyl ether, which was used as a dienophile and dipolarophile. The recycling of the support was achieved by palladium-catalysed direct O-vinylation of the residual alcohol functionality. Organocatalysed Mannich reaction was also studied through the immobilization of the aniline component onto the support. This strategy was first studied in solution with the p-(3-aminopropyloxy)aniline. However, its transposition on solid-phase was hampered by an additional cross-linking of the support

Full textTwelve new potentially anticancerous lipidic compounds belonging to the family of alkylglycerols have been synthesized a stereo- and enantiocontrolled manner starting from ricinoleic acid, oleic acid, stearolic acid and from 4-penten-1-ol. Four of these compounds were tested in vitro for inhibition of angiogenesis (one of the mechanisms which is implied in the tumoral growth), and one appeared to be a good inhibitor (70% at 12 μM). Sphingolipids form a family of biomolecules which are involved in diverse cellular processes such as growth, differentiation and apoptosis. Their small or large scale preparation is not often easy. In this context, we have developed a new efficient synthetic process which enabled to afford analogues of well defined stereochemistry

Full textLn this thesis, we have studied the reaction of FeCI3 with chlorosilyloxcyclopropanes prepared by addition of monochloro, dichloro, chloromethyl, chlorofluoro and chlorophenylcarbene on trimethylsilyl enols ethers. Generally, the reaction of FeCI3 in diethylether leads mainly to ß, ß dichlorocarbonyl compounds by cleavage of the cyclopropanic bond between the carbon atoms bearing heteroatoms. When the cyclopropanic carbon without heteroatom is totally substituted (case of dichlorosylyloxycyclopropanes) or monosubstitued (case of monochloro and chlorofluorosylyloxy cyclopropanes) we have also isolated products wich result from the cleavage of the cyclopropanic bond opposite to the carbon atom bearing the halogen. The dehydrochlorination of ß, ß dichlorocarbonyl compounds with a labile hydrogen in the α position have permitted to develop a novel method of synthesis of α, ß-ethylenic ß-chloro carbonyl compounds. Ln the case of chlorophenylstlyloxybtcyclo [n. L. O] alkanes we have obtained ῳ -unsaturated acids and esters resulting from the cleavage of the two cyclopropanics bonds adjacent to the silylxoy group. The same cleavage was observed in the case of totally substituted dichlorostly loxycyclopropanes in benzene

Full textWith the depletion of fossil fuel resources, the search for new alternatives such as biofuels produced from biomass has intensified. A wide variety of compounds can be produced by treating this biomass. Ethers are one of them and can be used as additives to conventional fuels or as fuel. To this end, it is necessary to have a better knowledge of the kinetics of the oxidation of these compounds which differ from conventional fuels by the presence of oxygen atoms in their structure, making the chemistry more complex. This thesis aims to develop kinetic mechanisms of the oxidation of simple ethers based on experimental data obtained in jet stirred reactor. The oxidation of four ethers at atmospheric pressure and high pressure (10 atm) was studied over a wide range of temperatures (450 - 1250 K) under different equivalence ratios (0.5 to 4). The mole fraction profiles of the reactants, products of combustion and main stable intermediates were measured by gas chromatography, infra-red spectrometry or photoionization mass spectrometry using synchrotron radiation. The results thus obtained then served as a basis for validating kinetic mechanisms modeling the oxidation of these species whose agreement with the measurements is globally satisfactory for compounds for which few studies are available

Full textThe present report describes the design and the synthesis of calix[4]arenes derivatives, as potential radioelement extractant from nuclear waste. Crown- and benzocrown-calix[4]arene compounds in the 1,3 alternate conformation simultaneously offer the selectivity of crown compounds and the preorganization of calixarenes in a more or less rigid conformation. The reaction conditions of intramolecular bridging or O-alkylation, based on the conformationnal isomerism process, lead to some original structures, fully characterized by RMN analysis. For the first time, a crown-ether modification was realised by introducing an acridinic fluorophore moiety on a known caesium selective crown calix[4]arene unit. Preliminary antimalarial activity results shown that some compounds described herein are potent inhibitors of Plasmodium Falciparum

Full textThe research work described in this manuscript is based on the green chemistry concept and within the frame of sustainable development which involve the use of raw materials from renewable resources and the development of eco-compatible process for the preparation of new products for food-processing, domestic or therapeutic applications. In this context, a new access to monosaccharide acetals and ethers (sorbitan and methyl glucoside) has been developed. The synthetic process is divided in two steps with an acetalisation or a transacetalisation as first reaction which allows to synthesize a new class of monosaccharide acetals. Then, a second step of acetal hydrogenolysis with palladium on charcoal and under hydrogen pressure has permitted access to sorbitan and methyl glucoside monoethers. Then, a one-step process and the use of intermediary short alkyl chain acetal as solubilizing agent has permitted to increase the yield and to consider an industrial development. Finally, these new molecules have been evaluated as surfactants, liquid crystals and antimicrobials and some of them have exhibited very attractive properties which could lead to potential applications in these fields

Full textThis work is devoted to the synthesis and characterisation of thiacalix[4]arene derivatives and to the study of their interactions with alkali, alkaline earth, heavy and transition metal ions. Two approaches have been used i) biphasic transfer of metal picrates from water into dichloromethane; ii) complexation in a single phase. The stability of the complexes in methanol and/or acetonitrile has been assessed by UV absorption spectrophotometry and potentiometry. The stoichiometry of the complexes in chloroform and the localisation of the cation in the ligand cavity have been determined by 1H NMR. The first part concerns the study of the extraction and complexation properties of two thiacalix[4]arenes-bis-crown-ethers. The results show that the replacement of methylene bridges by sulphur atoms decreases the extraction levels and the complex stability. However, these compounds can be more selective than calix[4]arenes, especially for caesium. The second part deals with the synthesis and study of the thiacalix[4]arene diethylamide, and the study of related p-adamantyl and the amidomorpholine derivatives. Results show the influence of the substituent in the para position and on the amide function on the binding abilities and the selectivity of these compounds. If a decrease of the performances of thiacalix[4]arenes amides with respect to corresponding calix[4]arenes is still observed, their selectivity for some heavy metal ions is improved. The third part reports on the synthesis of p-tert-butyl(thia)calix[4]arenes enriched in sulphur by substitution of the narrow rim by diethylthiophosphate functions, of corresponding calixarenes and of mixed derivatives bearing also ethyl ester groups. X-ray structures of some of the ligands were solved indicating their cone conformation. Extraction and complexation results showed that the presence of sulphur atoms in the molecules does not improve their affinity towards heavy metal cations. However, interesting selectivities are observed for silver and cadmium

Full textPolymacrocyclic compounds are of great interest due to their unique coordination properties. The first convenient synthetic approach to various polycyclic compounds containing several azacrown-ether moieties, to cryptands and supercryptands, based on azacrown-ethers, has been developed by Krakowiak and coworkers in the beginning of 1990s using simple nucleophilic substitution reactions. At present time heteropolytopic polymacrocyclic compounds, capable of forming polynuclear complexes with various metals, attract the utmost interest. In the majority of publications dealing with the synthesis of polymacrocyclic compounds non-catalytic approaches were applied, except for several porphyrin dyads and triads, which were obtained using Suzuki, Sonogashira and Heck reactions. The laboratory of organoelement compounds of Chemistry Department of Lomonosov Moscow State University has a great experience of the application of Pd-catalyzed amination reactions for the synthesis of polymacrocyclic compounds, nowadays Cu-catalyzed arylation of di- and polyamines is under investigation. Bearing it in mind we have found the research for Cu-catalyzed amination to be important in synthesis of polymacrocyclic compounds containing di- and polyamine linkers; as well as the synthesis of new types of polytopic polymacrocyclic conjugates, bearing azacrown-ether, porphyrin and calixarene moieties, by means of Pd- and Cu-catalyzed reactions; and studying their properties as metal cations detectors.The aim of the research is to develop catalytic synthetic approaches to polymacrocyclic conjugates, bearing azacrown-ether, porphyrin and calix[4]arene moieties, and to study their abilities as detectors for metal cations. For this purpose it is necessary to carry out the following investigations: 1) to study the regularities of Cu(I)-catalyzed amination of halogen derivatives of azacrown-ethers and porphyrins and to synthesize corresponding amino derivatives; 2) to develop the methods for the catalytic macrocyclization aimed at the synthesis of macrobicyclic and macrotricyclic compounds, containing diazacrown-ether, cyclen, cyclam and calix[4]arene moieties; 3) to introduce fluorophoric fragments (including porphyrins) into macrocyclic and macrobicyclic compounds; 4) to investigate metal cations binding by thus synthesized polymacrocycles using UV and fluorescent spectroscopy, and to find possible fluorescent and colorimetric detectors among them

Full textPolycyclic compounds and more specifically, spirocyclic ethers are of particular interest in fragrance chemistry. This thesis is dedicated to the development of new cycloisomerisations of enol ether derivatives by bismuth(III) triflate catalysis. In this way, a bibliographic study has been carried out on cyclisations catalysed by bismuth(III) triflate. A cycloisomerisation of allenic enol ethers has been developed for the straightforward synthesis of cyclopentene and dihydrofuran derivatives. New oxaspirocyclic compounds have been obtained starting from trifunctional substrates containing a cyclic enol ether and an additional hydroxyl group. The chemodivergence of this reaction has been studied by means of gold(I) catalysis to access different cyclopentenic structures via the preferential activation of the allene. A double cyclisation reaction has been developed leading to bridged polycyclic compounds featuring an oxaspirocyclic moiety. Mechanistic studies have been performed and a tandem cyclisation involving a 1,5-hydride shift has been studied. The double cyclisation of enantioenriched campholenic aldehyde derivatives has been investigated for the formation of tetracyclic diethers and tricyclic ketones. Most of the new compounds presented interesting notes, mainly in the aromatic and woody olfactory family

Full textWe focused in this work on particular compounds called solvo-surfactants that belong to the large family of hydrotropes. These low molecular weight nonionic amphiphiles possess simultaneously some properties of solvents (liquid state, volatility) and some of surfactants (reduction of interfacial tensions, self-association). Short chain ethoxylated alcohols CiEj, which are at present the most widespread ones, are controversial because of their genotoxicity. We focused here on new green solvo-surfactants: glycerol 1-monoethers CiGly1 (i < 6). In a first part, we developed the conceptual and experimental tools required for the comparison of their hydrophilic/lipophilic ratios and their solubilizing powers, by using the optimal formulation concept. We introduced the PACN (Preferred Alkane Carbon Number) notion that corresponds to the EACN (Equivalent ACN) of the oil leading to the attainment of the optimal formulation at 25°C without additive. This allowed us to build an absolute scale of classification, powerful tool that turned out to be particularly appropriate for the classification of hydrotropes, surfactants and oils. In a second part, we focused on glycerol 1-monoethers. Firstly we considered their synthesis and their fundamental physical properties, as well as their volatility, notably by vapour pressure measurements and calculations. Then we studied in details their behaviour in water and in ternary systems, performed several tests in the field of hard surface cleaning and evaluated their cytotoxicity and their biodegradability. These compounds turn out globally to be excellent candidates for the replacement of toxic glycol ethers
