Abstract:

The purpose of this study was to develop new catalytic methods to mediate carbon-carbon bond forming reactions with imines under mild conditions and in a general manner. We found that copper catalysts were compatible in cross-coupling of a range of mild organometallic reagents, providing simple, efficient routes to alpha-substituted amides and amines.<br>Chapter 2 of this thesis describes a new copper-catalyzed multicomponent synthesis of alpha-substituted amides. This reaction was developed based upon previous work in this laboratory, which showed that palladium catalysts were competent in St

For this reason, it is routine procedure in the drug discovery and development process to prepare the full matrix of possible stereoisomers of drug candidates for biological evaluation and to determine the stereochemical purity of these molecules. Despite many recent advances in asymmetric synthesis, the

Abstract:

Thesis advisor: Amir H. Hoveyda<br>Chapter 1. We have developed a catalytic method for enantio- and SN2’-selective allylic substitution of commercially available diborylmethane to trisubstituted allylic phosphates (pin = pinacolato). The transformations are catalyzed by NHC–Cu complexes (NHC = N-heterocyclic carbene). Products bearing quaternary stereogenic carbon centers are obtained in up to 86% yield (after oxidation), >98:2 SN2’/SN2 selectivity and 95:5 enantiomeric ratio (e.r.). Chapter 2. We have developed a facile multicomponent catalytic process that begins with a chemo- and site-se

Thesis advisor: Amir H. Hoveyda<br>Chapter 1. Ligand-Controlled Site-Selective NHC–Cu-Catalyzed Protoboration of Monosubstituted Allenes. Site-selective proto–boryl additions to monosubstituted allenes promoted by NHC–Cu complexes are disclosed. Synthetically useful 1,1-disubstituted and Z-trisubstituted alkenylboron compounds are afforded in high efficiency (71%–92% yield) and site selectivity (88% to >98%) through proper choice of NHC ligands. Mechanistic study with the assistance of DFT calculations indicates that protonation of 2-boron-substituted allylcopper complex occurs through six-

Abstract:

Two syntheses of non-cross-linked polystyrene-supported TADDOL-based phosphoric acid organocatalyst have been developed. The optimal polymer-supported catalyst 2.29d exhibited comparable catalytic activity to its small molecule counterpart in asymmetric Mannich-type reactions, and the syntheses of several chiral β-amino esters were demonstrated using 2.29d as catalyst. However, when this TADDOL-based phosphoric acid was immobilized on a polystyrene cross-linked with 1,4-bis(4-vinylphenoxy)butane, ie. JandaJelTM, the catalytic activity diminished in the first recycling and reuse of the

Abstract:

Cette thèse décrit le développement de nouvelles méthodes de catalyse à l’or et au cuivre pour la synthèse de composés hétérocycliques et de produits trifluorométhylés.Dans un premier temps, une synthèse d’allènes trifluorométhylés par catalyse à l’or a été développée, dont l’étape clé est un transfert d’hydrure 1,5. Cette méthode donne accès de manière efficace et sélective à une large gamme d’allène perfluoroalkylés dont le potentiel synthétique a également été démontré.Le pouvoir catalytique de l’or a alors été utilisé dans une synthèse de 2H-1,3-oxazines reposant sur une cyclisation de typ
