cyclopropenes to imines by leveraging the synergy between photoredox and asymmetric cobalt catalysis. This protocol facilitated the synthesis of a series of chiral functionalized cyclopropanes with high yield, enantioselectivity, and diastereoselectivity (44 examples, up to 93% yield and >99% ee). A possible reaction mechanism involving cyclopropene desymmetrization by Co–H species and imine addition by
在此,我们利用光氧化还原和不对称钴催化之间的协同作用,设计了一种环丙烯去对称加成反应。该方案促进了一系列具有高产率、对映选择性和非对映选择性的手性官能化环丙烷的合成(44 个实例,产率高达 93% 且 >99% ee)。提出了一种可能的反应机制,涉及 Co-H 物种的环丙烯去对称化和 Co-烷基物种的亚胺加成。这项研究为重要的手性环丙烷提供了一条新途径,并扩展了不对称金属光氧化还原催化的前沿。
