One aspect of the present invention relates to methods for the transition-metal-catalyzed asymmetric 1,4-addition of a nucleophile, e.g., hydride, to cyclic and acyclic enoates and enones. In certain embodiments of the methods of the present invention, the transition metal catalyst consists essentially of copper and an asymmetric bidentate bisphosphine ligand.
本发明的一个方面涉及过渡金属催化的不对称1,4-核亲电体(例如氢化物)对环状和非环状烯酸酯和烯醇的加成方法。在本发明的某些实施例中,过渡金属催化剂主要由铜和不对称双膦双膦配体组成。
