资源简介：
A copper-catalyzed asymmetric Mannich reaction between glycine Schiff bases and ketimines has been developed. This method afforded 2-oxindole-based chiral syn-α,β-diamino acid derivatives in high yields (89–99%) with good to excellent diastereoselectivities (≤98:2 dr) and excellent enantioselectivities (95–99% ee).
