Chiral β-Aminophosphine Oxides as Ligands for Ruthenium Assisted Enantioselective Transfer Hydrogenation of Ketones.

Abstract Enantiopure β-aminophosphine oxide ligands have been synthesized and used in asymmetric transfer hydrogenation of ketones. Optically active alcohols are obtained in high yields and with up to 84% enantiomeric excess.
