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. Transition metal-catalysed enol formation from allylic alcohols : Isomerisation, C−C and C−F bond formations
Abstract : This thesis describes the isomerisation of allylic alcohols into enols and enolates catalysed by transition metal complexes. The transformation has been used to prepare both unsubstituted and α-substituted carbonyl compounds. Significant attention has been given to the mechanistic aspects of the reactions. READ MORE

3. 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

4. Palladium-catalyzed Allylic C-H and C-OH Functionalization. Reactions of the Obtained Allylboronic Acids
Abstract : This thesis is focused on the studies of two major transformations. The first transformation deals with the development of palladium-catalyzed selective allylic trifluoroacetoxylation reactions based on C-H functionalization, whereas the second comprises the synthesis and isolation of allylboronic acids using diboronic acid B2(OH)4 as boron source.

5. Development of New Synthetic Routes to Organoboronates by Catalytic Allylic Substitution and C-H bond Functionalization
Abstract : This thesis describes the development of new catalytic methods for the synthesis and application of organometallic reagents, mainly focusing on allylboronic acid derivatives. Thus, palladium pincer-complex catalysis has been applied for extending the scope of palladiumcatalyzed borylation reactions in the synthesis of regio- and stereodefined functionalized allylboronic acid derivatives.
