Abstract
The asymmetric hydrogenation of aromatic ketones catalyzed by iridium complexes was investigated in the presence of chiral damines and achiral phosphines. The catalytic system with triphenylphosphine and 9-amino(9-deoxy)epicinchonine exhibited high activity and enantioselectivity in the asymmetric hydrogenation of simple aromatic ketones. A series of simple aromatic ketones were hydrogenated completely in just 2 h at room temperature with good ee value (up to 87%).
