High Yields

A highly enantioselective nucleophilic addition of ketones to versatile imines catalyzed by chiral PTC has been developed, and the process affords the Mannich reaction products with tertiary stereocenters in good to high yields and excellent enantioselectivities. This protocol is effective for gram scale reaction.
