Resumen

This doctoral thesis is divided into three sections: Part A, Part B and Part C. Part A is subdivided further into three chapters. In the first of these, an overview of the Julia olefination reaction process as well as its variants is provided, followed by a short description of the application of dithiane methodology in natural product synthesis. The second chapter describes the development of a new methodology based on Julia olefination of substrates derived from dithiane and dithiolane sulfones. Summary and conclusions then follow in chapter three. Part B of this thesis is also subdivided in

Resumen

Doctor of Philosophy (PhD), Science<br>A concise stereo-selective synthesis of a protected form of APTO 1, an unusual amino acid component of microsclerodermin C 2, was undertaken. Sequential Sharpless Asymmetric Aminohydroxylation (AA) and Asymmetric Dihydroxylation (AD) reactions were used to introduce the chiral amino and hydroxyl groups. Specific directing groups were chosen to ensure high regio- and enantio-selectivity in these reactions. The target compound was reached in a linear reaction sequence of fourteen steps. The strategy was designed to generate common intermediates which cou

Resumen

<p>This research has focused on extending the utility of previously synthesized 5-iodo-2,3-dihydro-4-pyridones. The initial conversion involved introducing a phosphonate group by nickel-catalyzed cross-coupling with the vinyl iodide at the C-5 position. Using a Horner-Wadsworth-Emmons reaction, the phosphonate ester was then converted to various olefins in moderate to high yields. Having an aldehyde present on the substituted 5-(diethoxyphosphoryl)--acylpiperidin-4-one allowed cyclization to occur thereby providing a bicyclic enone.<P>

This Thesis describes the development of telescoped rhodium(II)-catalysed transformations of α-diazo(diethoxyphosphoryl)acetates for the formation of α-methylene-γ-butyrolactones. An overview of synthetic approaches to α-methylene-γ-butyrolactones is given in Chapter 1, in addition to a discussion of published Rh(II)-catalysed C–H insertion reactions. Previous efforts in the Taylor group have established effective methods for the synthesis of α-methylene-γ-butyrolactones, although these require relatively complex functionality in the precursors. The research in this Thesis focuses on the devel

O presente trabalho descreve 3 abordagens divergentes para obtenção do esqueleto bicíclico presente nos alcaloides indolizidínicos. A primeira abordagem consiste no desenvolvimento de um novo método de preparação de diazocetonas α,β-insaturadas a partir da reação de Horner-Wadsworth-Emmons (HWE) entre diazofosfonato e aldeídos. As dizocetonas α,β-insaturadas obtidas foram utilizadas como bloco de construção do esqueleto cabocíclico indolizidínico, onde o intermediário chave foi obtido através do rearranjo de Wolff.

Les antalgiques utilisés aujourd’hui sont des produits anciens et plusieurs d’entre eux datent du 19ème siècle. La morphine demeure l’antalgique de référence pour les douleurs dites par excès de nociception, mais elle est à l’origine d’effets indésirables gênants et graves. Il a été démontré que l’effet antalgique de la morphine passait par l’activation des canaux potassiques TREK-1. Les travaux de recherche ont donc comme objectif la recherche d’antalgiques originaux activateurs de TREK-1.

Resumen

The Wittig reaction has been investigated with the use of a molecular modeling approach utilizing empirical molecular mechanics calculations (MMX) and semiempirical molecular orbital methods (MNDO-PM3). The MNDO-PM3 method reproduces the geometric and thermodynamic parameters, previously calculated using a more elaborate ab initio molecular orbital approach, of the "mythical Wittig half-reaction". MNDO-PM3 calculations and subsequent analyses using bond orders and localized molecular orbitals indicates that the transition states of the mythical Wittig half-reaction and the Wittig half-reaction
