The enantioselective, copper/phosphoramidite-catalyzed 1,4-addition of dialkylzinc reagents to acyclic dienones is described. The products of this reaction, obtained with enantioselectivities of up to 95 %, can be further functionalized by a second conjugate addition, or employed in an enolate trapping, ring-closing metathesis protocol.
