1. Catalytic Regio- and Stereoselective Reactions for the Synthesis of Allylic and Homoallylic Compounds
Abstract : This thesis is focused on two main areas of organic synthesis, palladium-catalyzed functionalization of alkenes and allylic alcohols, as well as development of new allylboration reactions.We have developed a palladium-catalyzed selective allylic trifluoroacetoxylation reaction based on C−H functionalization.

2. Synthesis of Organoboronic Acids and Applications in Asymmetric Organocatalysis
Abstract : Allyl- and allenylboronic acids are valuable reagents in organic synthesis due to their configurational stability and high reactivity. Few allyl- and allenylboronates are commercially available. Therefore, both the preparation and synthetic application of these organoboronic acids are subjects of study. READ MORE

3. Synthesis of functionalized allylic, propargylic and allenylic compounds : Selective formation of C–B, C–C, C–CF3 and C-Si bonds
Abstract : This thesis is focused on the development of new palladium and copper- mediated reactions for functionalization of alkenes and propargylic alcohol derivatives. The synthetic utility of the 1,2-diborylated butadienes synthesized in one of these processes has also been demonstrated. READ MORE

4. Silaborations of Unsaturated Compounds
Abstract : This thesis deals with the development of transition metal-catalyzed silaborations of 1,3-dienes and 1,6-enynes. The first part of the thesis describes the development of the enantioselective 1,4-silaboration of 1,3-cyclohexadiene. A number of chiral metal-ligand complexes were evaluated. READ MORE

5. Synthesis of chiral allyl and propargyl boronates by organocatalytic carbene insertion to carbon-boron bonds
Abstract : This thesis describes the development of a novel organocatalytic method for the synthesis of chiral allyl- and propargyl- organoboron compounds with high enantioselectivity. These organoboron species are versatile building blocks in asymmetric synthesis.We have developed a new efficient homologation method of alkenyl boronic acids. READ MORE
