Full textThe development of rapid and efficient syntheses of complex molecules from simple starting substrates using a minimum of steps is a real challenge of contemporary organic chemistry. In this context, multicomponent reactions, thanks to their ability to create several one-step bonds, offer a high efficiency in synthesizing structures of great molecular complexity. Moreover, organometallic catalysis has developed considerably in recent years, becoming a tool of choice for the formation of carbon-carbon bonds. The Tsuji-Trost reaction is specially well known in this field.In this thesis, the discovery of the original post-condensations from the adducts obtained by multicomponent reactions involving isonitrile is the major axis of our research. These reactions allow efficient access to a wide range of heterocyclic compounds.First, we have developed a new efficient pathway for the synthesis of indolylacetamides via the Passerini/Friedel-Crafts cascade from the Passerini adducts and indole in the presence of a Lewis acid. A one-pot version of this cascade has been also developed.Furthermore, we have exploited the reactivity of N-monosubstituted hydrazones as 1,3-bis-nucleophile in order to prepare various 2-pyrazoline derivatives via a pallado-catalyzed Tsuji-Trost/Cyclisation cascade from the Passerini adducts or Phosphonates. In order to prepare enantioselectively enriched 2-pyrazolines, the enantioselective version of this cascade was also realized from the Passerini adduct.Finally, the development of a new Tsuji-Trost/Cyclization cascade from the Passerini adducts and the allyl methyl carbonate provide straight fast and efficient access to oxazolidine-2,4-diones heterocyclic units by exploiting the carbon dioxide generated in situ

Full textThe use of Brönsted superacids (TfOH and Tf2NH) or Lewis superacids (M(n)(OTf)n and M(n)(NTf2)n) in organic synthesis presents a high interest in a wide number of reactions, particularly for the C-O, C-N and C-C bond formation involving the electrophilic activation of a double bond. These superacids could be used in sub-stoichiometric amounts whiole remaining more active and selective than more conventional Lewis acids, therefore improving the Green Chemistry aspects of our studies. We have used these catalysts to carry out Friedel-Crafts type reactions, tandem Friedel-Crafts-hydroalkoxylation processes and cycloisomerisations. The polyfunctionalised compounds for which a novel and efficient access is proposed present potential applications in medicinal, agricultural and perfume chemistry. A first chapter is devoted to the bibliographical studies of the various topics presented in this manuscript. In a second chapter, the Friedel-Crafts type allylation reaction from aromatic cycles, phenolic or not, have been studied and oriented towards the synthesis of valuable chemicals of industrial relevance. In a third chapter, mechanistic studies based on kinetic measurements and theoretical calculations on this reaction are presented. In a fourth chapter, cyclisation reactions of polyinsaturated compounds such as 1,6-dienes and aza-dines are presented. The cycloisomerisation of substituted 1,6-dienes allowed the access to several new compounds of interest in fragrance chemistry, a central interest of our laboratory. The application of the catalytic systems studied in the synthesis of compounds with odorant properties has

Full textAromatic polyfunctionalised compounds constitute an important class of intermediates and may present a wide scope of applications not only in the pharmaceutical field, but also in flavour and fragrance chemistry. The scope of this work was focused on the elaboration of a catalytic system promoting allylation of aromatics compounds by Friedel-Crafts method and intramolecular cyclisation reaction. Trifluoromethanesulfonate catalysts [M+n(OSO2CF3)n] are strong Lewis acids, considered as Lewis « superacids ». The allylation of various aromatic compounds, using acetates as the allylating agents has been developed. The method requires only a low amount of In(OTf)3 (1 mol%), operate at room temperature and the target molecules are obtained in yields of 50-90%. Allylation reactions with phenol derivatives have also been examined in catalytic reactions. Products involving intramolecular cyclisation are obtained with good yields. The same method is also extended for intramolecular Friedel-Crafts alkenylation reactions. Products are obtained quantitatively. A complementary study with chiral allylic acetate and other experiences led to a proposed reaction mechanism

Full textFriedel-Crafts alkylation reaction is one of the most fundamental C-C bond forming reactions in organic synthesis. This work concerns the study of Friedel-Crafts alkylation reaction involving various arenes and electrophiles such as imines and trifluoropyruvates. The addition of electron-rich aromatic compounds to imines, known as the aza-Friedel-Crafts reaction has been realized in the presence of a catalytic amount of samarium diiodide. This one showed good activity and provided access to new products such as triarylmethanes, a-amino esters and diarylamines. For the latter two compounds, a second Friedel-Crafts reaction, catalyzed by samarium diiodide, was performed using an aromatic compound different from the first step. This methodology has provided new unsymmetrical diarylesters and triarylmethanes. The study of the asymmetric aza-Friedel-Crafts reaction was also undertaken using samarium iodobinaphtholate as a chiral catalyst; maximum selectivity of 78% is then obtained. The enantioselective addition of various indole derivatives to alkyl trifluopyruvates is described in the presence of a new catalytic system based on ytterbium triflate and chiral pyridylalkylamines. Good yields and high enantioselectivities (up to 83% ee) in the Friedel-Crafts alkylation were obtained. This is the first report concerning the use of a chiral ytterbium complex in asymmetric Friedel-Crafts alkylation reactions. Moreover, the alkylation of anisole, phenol and naphthols by methyl trifluopyruvate was affectively performed in the presence of iron chloride (II) and indium chloride (III)

Full textThe work which was carried out for this PhD Thesis was based on the synthesis of BETA zeolite, supported on preshaped silicon carbide (SiC) or as nanowire form, and their uses as catalyst in liquid phase Friedel-Crafts acylation : first, the benzoylation of anisole by benzoyl chloride and second, the acylation of anisole by acetic anhydride. The first part of the PhD Thesis presents the synthesis of BETA and ZSM-5 zeolites, coated on silicon carbide (SiC) in different forms : grains, extrudates and foam. Silicon carbide exhibits high thermal conductivity, high resistance towards oxidation, high mechanical strength and chemical inertness, properties required for heterogeneous catalyst supports. It was efficiently used as support for dispersing BETA zeolite. The possibility of preparing BETA coated on SiC with a more open shape, i. E. Monolith, allows the use of these supported catalysts for a high rate reaction, with a minimum diffusion limitation. In a second part, we synthesized BETA zeolite in a non aqueous synthesis middle, with carbon multiwalled nanotubes as a shape matrix. We carried out these synthesis under hydrothermal and non-hydrothermal conditions. Finally, all the synthesized composites were used as catalysts for Friedel – Craft benzoylation and acetylation in both reaction modes : slurry and fixed-bed. Comparisons between our catalysts and a commercial bulk BETA are also reported, and show that catalytic activity and stability can be improved by supporting the zeolite

Full textThe search for new methods for the acquisition of physical and chemical reactions by limiting the effect on humans is of great importance for modern chemistry. The use of new miniaturized tools can limit the quantities of chemicals used while increasing research productivity. Indeed, the study of the various parameters monitored simultaneously increases the number of experimentsfor a given time. Nevertheless, this step must be performed after prior determination ofthe key parameters of the reaction by the use of high flow tools such as robotics. These tools are used for optimization and the search for new synthetic pathway of a reaction of industrial interest. In addition, to meet the interests of heterogeneous catalysis in industry for easier separation and recycling of these catalysts, we have developed two miniaturized tools. These allow the study and data acquisition of chemical reactions catalyzed by solid. Development was registeredin two stages : a physical characterization tools and the study of an industrial model reaction, the acylation of anisole with zeolite catalysts
