The rational design and implementation of enantiodivergent enamine catalysis is reported. A simple secondary amine catalyst, 2‐methyl‐l‐proline, and its tetrabutylammonium salt function as an enantiodivergent catalyst pair delivering the enantiomers of α‐functionalized aldehyde products in excellent enantioselectivities. This novel concept of designed enantiodivergence is applied to the enantioselective
报道了对映异构烯胺催化的合理设计和实施。简单的仲胺催化剂2-甲基-1-脯氨酸及其四丁基铵盐可作为对映体催化剂对,以优异的对映选择性提供α-官能化醛产物的对映体。设计对映体发散的这一新颖概念适用于醛类的对映选择性α-氨基化,醛醇和α-氨基羟化/α-羟基胺化反应。
