3. New Methods for the Synthesis of Vicinal Stereocenters : Palladium-Catalyzed Domino Reactions and Asymmetric Transfer Hydrogenation
Abstract : In this thesis the synthesis of vicinal stereocenters is investigated in two distinct contexts, namely the construction of 3,3-disubstituted oxindoles and the synthesis of b-hydroxy-a-amino acids. Both scaffolds are prevalent in a range of natural products and biologically relevant compounds and, therefore, methods for their synthesis are of great import. READ MORE

4. Stereoselective Nucleophilic Additions to Aldehydes and Development of New Methodology in Organic Synthesis
Abstract : This thesis is divided into four separate parts with nucleophilic addition to aldehydes as the common feature in three of them.The first part deals with the investigation of the stereochemical induction and elucidation of the factors that dictate the p-facial selectivities in Mukaiyama aldol addition to a- and a,b-heteroatom substituted aldehydes.
