Abstract
Remarkable additive effects of imides and 1,3-indandione were found in an iridium-BICP catalyzed asymmetric hydrogenation of imines. The hig hest enantioselectivity of 95% ee has been obtained for the hydrogenat ion of 2,3,3-trimethylindolenine catalyzed by an Ir-BICP catalyst. (C) 1998 Elsevier Science Ltd. All rights reserved.
