The regioselective and enantioselective Cu(II)-catalyzed 1,4-conjugate addition of diethylzinc reagent to nitrodienes is described. With 0.25 mol % of Cu(OAc)2 and chiral amidophosphine ligand L3, the 1,4-addition products were produced with a complete regioselectivity, high yields (81–98%), and excellent enantioselectivities (87–97% ee) in a short reaction time.
