摘要

This thesis has been done under the supervision of Professor Olivier Riant. We developed a new cooperative dual catalysis strategy based on a Cu~1/Pd~0 system. This strategy allowed us to successfully access/ α-allylated ketones diastereoselectively as well as enantioselectively. In a later point, we also developed two synthetic pathways to generate unprecedented (NHC)Cu' bifluoride complexes. We tested the activity of these complexes in several known Cu~1-catalyzed reactions, and consequently established the first Cu'-catalyzed diastereoselective allylation of (R)-N-tert-butanesulfinyl aldimines. The method enables efficient, simple and general synthesis of enantiomerically enriched homoallylic amines at room temperature in high yields.
