Highly Effective Chiral Dipyridylphosphine Ligands:Synthesis, Structural Determination, and Applications in the Ru-Catalyzed Asymmetric Hydrogenation Reactions

摘要

New chiral atropisometric dipyridylphosphine ligands have been prepared through a high-yield, relatively facile synthetic protocol. Preliminary results in the ruthenium-catalyzed enantioselective hydrogenation of olefins and ketoesters are described.
