1. Novel Pincer Complex-Catalyzed Transformations : Including Asymmetric Catalysis
Sammanfattning : 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. LÄS MER
2. Asymmetric Catalysis : Ligand Design and Conformational Studies
Sammanfattning : This thesis deals with the design of ligands for efficientasymmetric catalysis and studies of the conformation of theligands in the catalytically active complexes. All ligandsdeveloped contain chiral oxazoline heterocycles. LÄS MER
3. Chiral Pyridine-Containing Ligands for Asymmetric Catalysis. Synthesis and Applications
Sammanfattning : This thesis deals with the design and syntheses of chiral,enantiopure pyridinecontaining ligands and their applicationsin asymmetric catalyis.Chiral pyridyl pyrrolidine ligands and pyridyl oxazolineligands were synthesized and employed in thepalladium-catalysed allylic alkylation of 1,3-diphenyl-2-propenyl acetate with dimethyl malonate. LÄS MER
4. Asymmetric catalysis : ligand design and microwave acceleration
Sammanfattning : This thesis deals partly with the design and synthesis ofligands for use in asymmetric catalysis, and partly with theapplication of microwave heating on metal-based asymmetriccatalytic reactions.Enantiomerically pure pyridyl alcohols and bipyridylalcohols were synthesized from the chiral pool for future usein asymmetric catalysis.

5. Bispyridylamides as ligands in asymmetric catalysis
Sammanfattning : This thesis deals with the preparation and use of chiralbispyridylamides as ligands in metal-catalyzed asymmetricreactions. The compounds were prepared by amide formation usingdifferent coupling reagents. LÄS MER
