We report copper(I)‐catalyzed enantio‐ and diastereodivergent borylative coupling of styrenes and imines to produce enantiomerically‐enriched α,β‐dibranched γ‐boryl amine derivatives. Each of the four possible stereoisomers of the products, derived from the two contiguous stereocenters, was selectively accessible by choosing a proper chiral ligand for the copper catalyst. This method, which combines
我们报告了铜(I)催化的苯乙烯和亚胺的对映异构和非对映异构的硼烷基偶联,生成对映体富集的α,β-二支化γ-硼胺衍生物。通过为铜催化剂选择合适的手性配体,可以选择性地获得衍生自两个连续立体中心的四种可能的立体异构体中的每一种。该方法结合了催化剂控制的立体发散性和从链节基序(即C-B键)衍生的结构发散性,为解决伴随精确手性控制的分子结构多样性的构建提供了一种策略。
