  γ-amino butyric acid derivatives were synthesized in good enantioselectivities via the Cu-catalyzed asymmetric conjugate reduction of γ-phthalimido-α,β-unsaturated carboxylic acid esters using Cu(OAc)2·H2O as a catalyst precursor, (S)-BINAP as a ligand, PMHS as a hydride source, and t-BuOH as an additive. The methodology has been applied successfully to the enantioselective synthesis of a chiral pharmaceutical

  以Cu（OAc）2·H2O为催化剂，通过Cu催化γ-邻苯二甲酰亚胺-α，β-不饱和羧酸酯的不对称共轭还原反应，合成了一系列具有良好对映选择性的手性β-芳基取代的γ-氨基丁酸衍生物。催化剂前体，（S）-BINAP作为配体，PMHS作为氢化物源，t-BuOH作为添加剂。该方法已成功应用于手性药物（R）-baclofen的对映选择性合成。
