The chiral cationic rhodium aminophosphine-phosphinite complexes 4-6 w
ere applied successfully in the asymmetric hydrogenation of alpha- (7-
9), beta- (10, 11) and gamma- (12) aminoketone hydrochloride derivativ
es leading to the corresponding aminoalcohols in up to 97, 93, and 92
% enantiomeric excesses for the three types of substrates respectively
