Les travaux présentés dans ce manuscrit s’inscrivent dans le contexte général de l’essor de la biocatalyse et de son utilisation en synthèse organique. Le thème principal porte sur l’étude et le développement de différentes voies d’accès stéréosélectives à des acides alpha-aminés bêta-hydroxylés substitués. L’utilisation d’un biocatalyseur permettant d’accéder à des acides alpha-aminés bêta-hydroxylés par une aldolisation entre la glycine et divers aldéhydes, en présence de phosphate de pyridoxal, a été étudiée. Des aldéhydes aliphatiques, aromatiques et hétéroaromatiques ont pu être impliqués

Abstract:

The research described in this thesis focuses on the catalytic acylative kinetic resolution (KR) of aromatic secondary alcohols, using a planar-chiral 4-(dimethylamino)pyridine (DMAP) organocatalyst. In the first part of this thesis, the substrate scope of the above mentioned process was expanded to aromatic secondary alcohols that contain an extra functional group in the alkyl moiety, such as 1,2-azido alcohols, 2-hydroxy-2-aryl-ethylphosphonates and 2-hydroxy-2-aryl esters. Thus, the preparation of highly functionalized compounds in their enantiomerically pure form with excellent enantiomeri

The development of new, efficient methods for the formation of carbon-carbon bonds using transition metal catalysis has broad applications in the field of organic chemistry and is the key to efficient chemical synthesis. Many efforts had been made to develop efficient ways to make these linkages particularly with the aid of metals such as Rh, Pd, Ni, Ru and Cu. Our group is primarily focused on exploring how these transition metals can activate typically inert functional groups, paving way to new synthetic routes to construct more complex molecules.

Abstract:

Heterocycles were prepared through the geminal acylation of 2-methoxyoxazolidines with 1,2-bis(trimethylsilyloxy)cyclobutene. It was found that when water was excluded from the standard reaction conditions, regioselectivity of the ring expansion step was reversed, resulting in preferential rupturing of the endocyclic C-O bond instead of the C-N bond. Further cyclization resulted in the generation of 6,5-fused ring systems. The aqueous procedure was found to be applicable to 1,2-bis(trimethylsilyloxy)cyclopentene, resulting in the analogous 6,6-fused ring systems, while the anhydrous procedure

Abstract:

碩士<br>國立臺灣師範大學<br>化學系<br>101<br>This thesis is divided into two parts: direct β–acylation of 2-Arylidine-1,3-indandiones catalyzed by organophosphanes (part I), and synthesis of indoles and furans via chemoselective intramolecular Wittig reactions (part II). In the first part, we have developed a new synthetic method for β–acylation of 2-Arylidine-1,3-indandiones. In the reaction only catalytic amount of organophosphane was required to provide acylated products in up to 98% yield. Starting from various substituted 2-arylidene-1,3-indandiones and acyl chlorides in the presence of Et3N. Further
