Grignardreagents undergo enantioselective (up to 86% ee) copper-catalyzed S(N)2' substitution on achiral allylic chlorides. The reaction is wide in scope for both the Grignardreagent and the allylic substrate. The resulting terminal alkene could be submitted to intra- or intermolecular metathesis to afford newchiral synthons. The experimental conditions are compatible with a one-pot overall sub
