The Copper Mediated Barbier Reactions of α,β-Unsaturated Ketones: Regioselective Conjugate and 1,2-Addition
摘要:
The one-pot reaction of isophorone and other alpha,beta-unsaturated ketones with alkyl and aryl halides in the presence of magnesium and a copper salt ("Barbier" conditions) leads to the regiospecific formation of 1,4-addition products; the use of lithium leads to regioselective 1,2-addition.
