摘要

A highly enantioselective Mannich reaction between 3-substituted-2H-1,4-benzoxazines and acetone catalyzed by lipase from wheat germ type I (WGL) is described. Enantioselectivity of up to 95% ee was achieved in DMSO at 25 degrees C. This research provides a new and simple method for the synthesis of beta-amino ketone derivatives and promotes the development of enzyme-catalyzed Mannich reactions.
