Abstract
Equation presented. Full conversion and enantioselectivities up to 83% have been obtained in the conjugate addition reactions of diethyl zinc to Michael acceptors catalyzed by well-defined (chiral) copper(I) aminoarenethiolates. Interesting differences between organozinc or Grignard reagents have been found: for cyclic enones R2Zn reagents afford better results, whereas earlier work showed that RMgX reagents react more selectively with acyclic enones.
