抄録

Carbolithiation of 3-(trimethylsilyl)acrylamide and cinnamamide derivatives gave the corresponding 3-substituted (Michael) and/or 2-substituted (contra-Michael) adducts. The regioselectivity depends on the nature of alkyllithium reagents. In the carbolithiation with <I>n</I>-alkyllithiums, the presence of <I>t</I>-BuOK caused dramatic change of the addition mode and the contra-Michael adducts were obtained exclusively.
