  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

  The effectiveness of N,N-dimethyl-2-amino-1,2-diphenylethanol as a chiral ligand was significantly improved via simple hydrogenation of the phenyl rings. Both the catalytic activity and the enantioselectivity of the resulting new ligand in the asymmetric conjugate addition of diethylzinc to enones were found to be superior to the original phenyl analog.

  N，N-二甲基-2-氨基-1,2-二苯基乙醇作为手性配体的有效性通过苯环的简单氢化而得到显着改善。发现二乙基锌与烯酮的不对称共轭加成中所得新配体的催化活性和对映选择性均优于原始苯基类似物。
