A highly regioselective Cu(I)-catalyzed anti-carbometallation of secondary terminal propargylicalcohols with 1° alkyl or aryl Grignard reagents affording 2-substituted allylic alcohols was developed. By using this method, optically active allylic alcohols can be prepared from the optically active propargylicalcohols without obvious loss of the enantiopurity. The cyclic organometallic intermediate
