1. Development and applications of intramolecular palladium-catalyzed 1,4-oxidations of conjugated dienes
Sammanfattning : .... LÄS MER
2. Iridium Catalysed Asymmetric Hydrogenation of Pyridines
Sammanfattning : This thesis presents the hydrogenation of substituted pyridines using N,P-ligated iridium catalystsin homogeneous media. These iridium catalysts were developed within this research group in thepast decade. This method of hydrogenation is highly stereoselective, and in several cases good to excellent ees were obtained.

3. Asymmetric Hydrogenations of Imines, Vinyl Fluorides, Enol Phosphinates and Other Alkenes Using N,P-Ligated Iridium Complexes
Sammanfattning : The research described in this thesis is directed toward the efficient, enantioselective synthesis of chiral products that have useful functionality. This goal was pursued through catalytic asymmetric hydrogenation, a reaction class that selectively introduces one or two stereocenters into a molecule in an atom-efficient step. LÄS MER
4. Chemo- and Enantioselective Hydrogenations : The Struggle of Expanding the Substrate Scope of Iridium Catalyzed Asymmetric Hydrogenations of Olefins
Sammanfattning : The asymmetric hydrogenation of olefins is a facile and popular method of reaching chiral products. Whereas ruthenium- and rhodium-catalyzed asymmetric hydrogenations have a long history, the use of iridium in this area is new but fast-growing. LÄS MER
5. Development of New Chiral Bicyclic Ligands : Applications in Catalytic Asymmetric Transfer Hydrogenation, Epoxidations, and Epoxide Rearrangements
Sammanfattning : This thesis describes the synthesis and application of new chiral bicyclic ligands and their application in asymmetric catalysis. The studies involved: [i] The development of novel chiral bicyclic amino sulfur ligands and their use in transfer hydrogenation. LÄS MER
