1. Stereoselective Nucleophilic Additions to α-Amino Aldehydes: Application to Natural Product Synthesis
Abstract : This thesis deals with the development and application of new synthetic methodology for stereo- or regioselective construction of carbon-carbon bonds in organic synthesis. The first part of this thesis describes the development of a divergent protocol for stereoselective synthesis of chiral aminodiols by employing Mukaiyama aldol additions to syn- and anti-α-amino-β-silyloxy aldehydes.

2. Design and stereoselective syntheses of Phe-Phe dipeptidomimetics
Abstract : Several stereochemically well characterized Phe-Phe dipeptidomimetics have been designed and synthesized. The Phe-Phe vinyl isostere was used as a key intermediate. The synthesized series of mimetics includes two isomeric epoxides, four 1,2-dihydroxyethylene isomers, two isomeric allylic alcohols and two isomeric allylic fluorides. READ MORE

3. Fine-tuning of the catalytic activity and selectivity of palladium pincer complexes
Abstract : This thesis is focused on optimization of the catalytic properties of so-called pincer complexes. This work involved synthesis of a large variety of palladium pincer complexes, which were applied in various organic transformations. READ MORE

4. Novel Pincer Complex-Catalyzed Transformations : Including Asymmetric Catalysis
Abstract : This thesis is focused on the development of new pincer complex-catalyzed transformations. Optimization of the catalytic properties (fine-tuning) was directed to increase the catalytic activity as well as the chemo-, stereo- and enantioselectivity of the complexes. READ MORE
