The highly enantioselective Michael addition of malononitrile to acyclic and cyclic alpha,beta-unsaturated ketones has been developed. The Michael reaction catalyzed by a primary amine derived from quinidine proceeded smoothly and provided the desired adducts with excellent enantioselectivities (83-97% ee).
