addition sequence by chiral primary amine catalysis, which offers a powerful alternative in the design of synthetically useful organocascade reactions (see scheme, EWG=electron‐withdrawing group). This method complements the Diels–Alder reaction for the one‐step synthesis of complex cyclohexane scaffolds with excellent optical purity.
伯胺的作用不同:无环α,β-不饱和酮通过手性
伯胺催化被活化成具有特征性的逐步双迈克尔加成序列,为合成有用的有机级联反应的设计提供了有力的选择(请参阅示意图,EWG =电子-退出小组)。该方法是Diels-Alder反应的补充,用于一步合成具有优异光学纯度的复杂
