11. Controlling the Reactivity and Selectivity in Iridium- and Rhodium-Catalyzed Asymmetric Hydrogenation
Abstract : The work presented in this thesis is mainly focused on the development of iridium- or rhodium-catalyzed asymmetric hydrogenation featuring a number of practical concepts including cascade reaction, kinetic resolution, desymmetrization, and dearomatization. The protocols rely on gaining control of the reactivity among different olefins or olefin precursor as well as maintaining chemo- and stereo-selectivity in the hydrogenation. READ MORE

12. Enzymatic Reduction of Ketones
Abstract : Methods have been studied for the production of chiral alcohols, which are of importance in organic synthesis of pharmaceuticals, agro-chemicals and fragrances, etc., through the enzymatic or microbial reduction of ketones. READ MORE

13. Allylic alcohols and aziridines from alkenes : Studies in asymmetric catalysis
Abstract : The development of methodology for asymmetric catalytic transformation of alkenederivatives is summarized. The studies concern the [a] Cu(I)-catalyzed allylic oxidation,[b] isomerization of epoxides to allyl alcohols, and [c] Cu(I)-catalyzed alkeneaziridination, respectively.[a] The preparation of exo-2-azabicyclo[2.2.

14. Hydrolases as Catalysts for Green Chemistry and Industrial Applications - Esterase, Lipase and Phytase
Abstract : The use of enzymes in industrial applications has been recognised for providing clean processes with minimal impact on the environment. This thesis presents studies on engineering of enzymes and enzyme-based processes in the light of green chemistry and environmental sustainability, and focuses on three hydrolases: esterase, lipase and phytase.

15. Homochiral crystals for selective synthesis
Abstract : Six new coordination compounds were prepared from monodentate sulfide ligands and copper(I) halides and their crystal structures were determined by single-crystal X-ray diffraction. The aim was to prepare coordination polymers that crystallize as conglomerates in order to use them in total spontaneous resolution. READ MORE
