Resumen
Antibiotic resistance is becoming ever more severe due in part to the increasing use of antibiotic drugs. One significant contributor to this problem is the production of β-lactamase enzymes that provide resistance to common β-lactam antibiotics. The scope of this research is to synthesize and study the β-lactamase inhibitors of 2-carbamoyl-4-oxo-1,5-diazabicyclo [3.2.1] octane derivatives. Currently the research process is in the beginning stages of synthesizing three compounds: (R)-hexahydro-6-oxopyrimidine-4-carboxylic acid (1a), hexahydro-2,2-dimethyl-6-oxopyrimidine-4-carboxylic acid (1b) and hexahydro-6-oxo-2-phenylpyrimidine-4-carboxylic acid (1c). The future steps are to synthesize (R) -3-(methoxycarbonyl)-hexahydro-6-oxopyrimidine-4-carboxylic acid (2a), (R)-dimethyl tetrahydro-4-oxopyrimidine-1,6(2H)-dicarboxylate (3a) and (R)-methyl hexahydro-6-oxopyrimidine-4-carboxylate (4a). All the compounds will be evaluated for the inhibitory activities against pure TEM-1 and P99 β-lactamase.

Resumen
Une méthode générale de synthèse des sels de pyridinium N-substitués par différents auxiliaires chiraux, une application de la réaction de Zincke, à partir des amines primaires chirales correspondantes, est décrite. Par réduction au borohydrure de sodium en milieu alcalin, ces sels de pyridinium conduisent aux dihydro-1,2 pyridines correspondantes dont les réactions de cycloaddition avec l'acrylate de méthyle ont été étudiées. Des composés azabicyclo[2. 2. 2]octane (isoquinuclidines), dont la configuration absolue a été établie, sont obtenus avec des e. D. De 20 à 33% et une bonne pureté optique. La réduction des sels de pyridinium dérivés des aminoalcools tel que la (R)-phénylglycinol dans les mêmes conditions conduit aux intermédiaires de type oxazolidine équivalent stable d'un sel de dihydro-2,5 pyridinium. L'alkylation stéréosélective de ces derniers par les réactifs de Grignard, suivie de l'élimination de l’auxiliaire donne accès aux alkyl-2 tétrahydro-1,2,3,6 pyridines optiquement active. L'intérêt de cette méthode générale pour l'élaboration des squelettes pipéridiniques, est illustré par la synthèse de la (R)-(+)-anatabine ainsi que la (S)-(+)coniine
The reaction of chiral primary amines with 2,4-dinitro phenyl pyridinium chloride, according to Zincke's procedure, leads to chiral pyridinium salts which can be reduced with NaBH4 in an alkaline medium to the corresponding 1,2-dihydropyridines bearing the chiral substituent on the nitrogen. Cycloaddition reactions of these dihydropyridines with methyl acrylate give isoquinuclidines in 20-33% d. E. Absolute configuration of optically pure isoquinuclidines separated from this diastereoisomeric mixture is established. On the other hand, reduction of pyridinium salts derived from amino alcohols such as (R)-phenyl glycinol in the same conditions leads to new oxazolidine-type intermediates which can be considered as 2,5-dihydropyridinium salt equivalents. Stereoselective alkylation followed by removal of the chiral auxilliary provides a simple access to enantio­ merically pure 2-alkyl 1,2,3,6-tetrahydropyridines. The usefulness of this methodology for the construction of optically pure piperidine derivatives is illustrated by the synthesis of (R)-(+)-anatabine and (S)-(+)-coniine

Resumen
L'engouement aujourd'hui pour la manipulation des propriétés électriques des supraconducteurs moléculaires dans le domaine des matériaux, nous a conduit à installer des gyroscopes au sein du cristal, pour que la propriété dynamique puisse moduler l'environnement électrostatique pouvant déboucher vers un nouvel ordre de charge et des structures ferroélectriques. Une machine moléculaire qui possède un rotor, un axe de rotation et des stators tel que le 1,4-diéthynylbicyclo[2,2,2]octane, a été choisie pour sa particularité à interagir avec la lumière, que l'on organise au sein du solide, sous forme de monocristaux appelés moteurs cristallins. La RMN CP/MAS sur poudre cristalline et monocristal a permis de caractériser le mouvement du rotor. Le développement d'une approche cristalline ajouté à la fonctionnalisation des rotors ont permis leur auto-assemblage et leur installation dans des architectures ouvertes organisées autour de cation métalliques (MOF,PCP,), ce qui a permis l'élaboration de matériaux multifonctionnels, dotés de la fonction dynamique, aux propriétés de conductivité ou de transition spin (SCO-MOF). Finalement, l'étude de systèmes cristallins dynamiques de basse dimentionnalité en optique non linéaire a permis de mettre en évidence le phénomène de photo-pilotage des gyroscopes par la lumière au sein du solide. le développement de systèmes plus élaborés permettra de mieux comprendre ce phénomène afin de l'utiliser dans des applications industrielles.

Ce travail decrit les rearrangements acido-catalyses des systemes 2-oxa-bicyclo(4. 2. 0) octanes: contribution a la synthese des cycles pontes b/c des mycotoxines de type trichothecene telles que l'anguidine: 1) voie lactone: l'addition photochimique de l'acetylene sur la lactone 15 n'est pas stereospecifique. De ce fait, aucun rearrangement n'a ete tente sur le cyclobutenyl carbinol b; 2) voie enone: differents alcools tertiaires 48 et 49, possedant le systeme 2-oxa-bicyclo(4. 2. 0)octane ont ete synthetises. Leur stabilite en presence de bf#3-et#2o ou d'acide formique ne conduit pas, dans les conditions douces etudiees, a la formation du systeme ponte (3. 2. 1) octane cible; 3) la stabilite de ces unites 2-oxa-bicyclo(4. 2. 0)octanes a ete confirmee dans le cas du compose 69 en presence de bf#3-et#2o. La formation de l'isomere 73 a partir de 69 implique la rupture de la liaison centrale par un mecanisme de type retroaldolisation; 4) l'etude des effets conformationnels des differents composes synthetises en r. M. N. #1#3c montre que ce squelette 2-oxa-bicyclo(4. 2. 0) octene est flexible.

It was known that the Bacillus megaterium Cytochrome P450 BM3 exhibits high substrates specificity to catalyzing its congenital substrates, fatty acids. In this study, cytochrome P450 BM3 proteins were successfully heterologously expressed in Escherichia coli. A mutated Ala74Gly, Phe87Val, and Leu188Gln strain was also validate for octane oxidation. After employing random mutation studies of the P450BM3 encoded sequences, we obtained the other three variants to study their octane activation chemistry without any alteration of P450 reductase encoded sequences. 2-octanol exhibiting a hydroxyl group at the sub-terminal carbon could be further oxidized via the iodoform reaction. The oxidation products were analyzed by GC and UV-visible Spectroscopy. The conversion ratio of C-H bond on the 2nd carbon of octane by bacteria could be quantities facilely and reliably. We anticipate deploying this method for selecting appropriate strains to achieve the C-H activation of sub-terminal hydrocarbon in more specific manner. In addition, the DNA of Pseudomonas putida Cytochrome P450cam (CamC) and Putidaredoxin (CamB) encoded sequences involved with the functions on camphor hydroxylation and catalytic redox suppliers, respectively, were constructed within the protein expression vectors pET 21a and 22b. Those constructed vectors were successfully transformed into the host, E. coli BL21 (DE3). The Putidaredoxin (CamB) protein could be expressed in E. coli heterlogously in the presence of IPTG.

A method to build the framework of bicyclo[2.2.2]octanes via 2-amino-1,3-dienes system with quinine-derived primary amine catalyst was disclosed. According to optimized conditions, cyclohexenones and 2-aryllidene-1,3-indanediones were dissolved in toluene at the room temperature, then 20 mol% of primary amine catalyst and 20 mol% of benzoic acid were added. The substituted bicyclo[2.2.2]octanones, bearing one spiro quaternary carbon and three chiral centers, were obtained in high yields (up to 91 %), excellent diastereoselective ( up to >20:1 dr) and enantioselective (98% ee). This reaction was also operated with cinnamaldehyde, 1,3-indandione and cyclohexenone, through Knoevenagel condensation/ [4+2] cycloaddition in one-pot manner to get desired product bicyclic with the high level of stereoselectivities (>20:1 dr, 97% ee).

This thesis focuses on acid-promoted intramolecular cyclization of O-silyl-protected 3-(3-arylpropargyltosylamino)methylcyclohex-2-en-1-ols and 2-methyl-2,3-epoxy-4-(3-arylpropargyl)cyclohexan-1-ones. Two major reactions are discussed. First, BF3•OEt2-promoted intramolecular cyclization/ fluorination of O-silyl-protected 3-(3-arylpropargyltosylamino)methylcyclo- hex-2-en-1-ols at room temperature under an atmosphere of nitrogen afforded N-containig spiro[4.5]dec-6-ene derivatives containing a C(sp2)-F bond. In this process, boron trifluoride diethyl etherate acts as both the Lewis Acid and the fluoride source. Second, TfOH-catalyzed cyclization of 2-methyl-2,3-epoxy- 4-(3-aryl-propargyl)cyclohexan-1-ones at room temperature under an atmosphere of nitrogen provided 7-benzoylbicyclo[3.2.1]octan-2-one. The Lewis Acid (FeCl3 or BF3•OEt2)-assisted cyclization of the same substrate in air at room temperature afforded aryl(halo)methylenebicyclo[3.2.1]octan-2-one de-rivatives containing a C(sp2)-halo bond (halo = Cl or F).

PART-1 Synthetic studies of the photochromic spiropyran dyes Abstract The major applications for the photochromic functional dyes are in the field of optical memory. In the past few years, these dyes combined with polymeric substrates to form several materials, which could be applied for the new high technology products, such as photochromic sunglasses, color filter, photochromic fiber, or ultraviolet indicator were developed expensively. The major purpose of this study is to synthesize different derivatives of spiro compound(1a).Other carrying vanious electron donating or electron withdrawing groups as R1, R2andR3 characteristics of different derivative are discussed as well. Synthesis of the indoleninium iodide 4 which is key intermediate for spiro compound(1a) is important in this study. PART-2 Synthetic studies of the 8-hydroxy octanic acid Abstract Hydroxy octanic acid(HOA 1) is an inhibiter and it’s very expensive.In 2003, SARS(Severe Acute Respiratory Syndrome) virus wreak people cruelly .This compound,HOA1,was discovered that it could kill SARS virus efficiently. Its function to destroy the microbes was also used to destroy Enterovirus and RNA flu virus. Because of these functions, this compound was used to make the products which can protect people’s health from virus. The purpose of this study is to design the compound methods for “HOA1 ” that focus on using inexpensive materials and simple reaction steps. Furthur more, it will address the possibility of industrial products. .
