   Sammanfattning : The synthesis of 2-aza-norborane derivatives is presented. The use of these compounds in preparation of Ir catalysts for asymmetric hydrogenations is described. The evaluation and optimization of the catalysts as well as the mechanistic aspects of the catalytic process are discussed. LÄS MER

3. 2. Development of highly modular ligands for use in asymmetric transition-metal catalyzed reactions

   Sammanfattning : The synthesis and evaluation of ligands for use in asymmetric transition metal catalyzed reactions is a widely used concept to achieve improved enantioselectivity in a variety of different transformations. The present thesis decribes the synthesis of a number of different oxazoline-based ligands and their use in titanum-catalyzed addition of diethyl zinc to aliphatic and aromatic aldehydes. LÄS MER
