Phosphoric Acid-Catalyzed Enantioselective Transfer Hydrogenation of N-Aryl-ortho-Hydroxybenzophenone Ketimines

The first enantioselective chiral phosphoric acid-catalyzed transfer hydrogenation of N-aryl-ortho-hydroxybenzophenone ketimines using a Hantzsch ester as hydrogen source was developed to afford, after removal of the N-aryl group, the corresponding chiral diarylmethylamines in high yields and enantioselectivities.
