  An enantioselective Cu(II)-catalyzed conjugate addition of dialkylzinc reagents to α,β- or α,β,γ,δ-unsaturated ketones with chiral cyclohexane-based amidophosphine ligands was developed. With 2 mol% of Cu(OAc)2·H2O/L5, the conjugate addition of diethylzinc to α,β-unsaturated ketones was achieved in good-to-excellent yields (up to 98%) and high enantioselectivities (up to 92% ee). This catalytic system

  BINAM-PHOS, participate in the copper-catalyzed asymmetric conjugate addition of organozinc reagents to enones. The incorporation of benzoyl derivatives on nitrogen atoms was crucial to promote the reaction. ­Notably, BINAM-PHOS derivatives gave the opposite major enantiomers to that obtained using BINOL-PHOS derivatives, which we have developed for the construction of multinuclear catalysts.

  A family of new chiral phosphoramidite ligands based on 3,3'-disubstituted (S)-BINOL have been successfully synthesized. The chiral phosphoramidite ligands were subsequently applied to the copper(II)-catalyzed enantioselective addition of diethylzinc to beta-substituted enones, giving the desired chiral adducts with enantioselectivities of up to 93% ee and high yields (up to 88%).
