Abstract:

This thesis concerned about the Ru-catalyzed C-H functionalizations on the synthesis of 2-arylindole unit, silylation of heteroarenes and preparation of aryne precursor. In the first project, we developed the Ru-catalyzed C2-H arylation of N-(2-pyrimidyl) indoles and pyrroles with nucleophilic arylboronic acids under oxidative conditions. Wide variety of arylboronic acids afforded the desired product in excellent yield regardless of the substituents or functional group electronic nature. Electron-rich heteroarenes are well suited for this method than electron-poor heteroarenes. Halides such as

Abstract:

Afin d'expliquer le contexte de mon travail de recherche, j'ai résumé dans le premier chapitre des informations mécanistiques générales sur l'arylation des liaisons C-H catalysée par le palladium et j'ai détaillé certains travaux sur l'arylation directe en relation avec mes travaux. Mes objectifs étaient d'étudier la réactivité de nouvelles unités synthétiques permettant l'accès direct à des composés bi-(hétéro)aryls ou à des dérivés du styrène. Ensuite, dans les chapitres 2 à 6, j'ai résumé mes travaux de recherche. J'ai étudié l’arylation directes en C2 du Methoxsalen par des chlorures de be

Abstract:

Au cours de cette thèse, nous nous sommes intéressés à l'activation de liaisons sp² et sp³ C-H catalysée par le palladium pour la préparation d'(hétéro)aryl-aryles et de biaryles. Cette méthode est considérée comme attractive pour l'environnement par rapport aux méthodes classiques, tels que Suzuki, Heck, ou Negishi. Tout d'abord, nous avons décrit que la C2-arylation directe de benzothiophènes peut être effectuée par un catalyseur du palladium en l'absence de ligand phosphine avec une grande sélectivité. Nous avons également démontré qu'il est possible d'activer les positions C2 et C5 de pyrr

Abstract:

Septinas compreendem uma conservada família de proteínas de ligação a nucleotídeo de guanina e formação de heterofilamentos. Em termos estruturais, elas possuem uma organização comum: um domínio GTPase central, uma região N-terminal e um domínio C-terminal, este último é predito para formar estruturas em coiled coil. Atualmente, o heterocomplexo de septinas humanas (SEPT2/SEPT6/SEPT7) mais bem caracterizado revela a importância do domínio GTPase na formação do filamento, todavia a ausência de densidade eletrônica para os domínios C-terminais faz com que sua função permaneça obscura.

Abstract:

This thesis describes the synthetic studies performed utilizing tridentate Schiff base Cr(III) complex catalysts towards the total synthesis of ()-lasonolide A resulting in the completion of synthetic efforts towards the C17-C25 segment. Further summarization is also given on completion of the C7-C16 segment and an overview of future directions toward to the total synthesis of ()-lasonolide A. Both tetrahydropyrans C7-C11 and C19-C23 were to be constructed utilising an asymmetric hetero-Diels–Alder protocol involving Jacobsen’s hetero-Diels–Alder catalyst providing a means to generate a numb
