资源简介：
A new P-chiral phosphine bis(sulfonamide) ligand has been developed that allows the Cu-catalyzed enantioselective conjugate addition of Et2Zn to acyclic aliphatic enones. The reactions proceed with excellent levels of enantioselectivity (90−95% ee) with a range of enone substrates, involve the use of only 1.2 equiv of Et2Zn, and give best results at ambient temperature.
