biologically active compounds. Although methods for the synthesis of thermodynamically favored, disubstituted cyclohexanes are well established, a reliable and modular protocol for the synthesis of their stereoisomers is still elusive. Herein, we report a general strategy for the modular synthesis of disubstituted cyclohexanes with excellent kinetic stereocontrol from readily accessible substituted methylenecyclohexanes
取代的六元环烃是生物活性化合物的常见成分。尽管合成热力学有利的二取代环己烷的方法已经很成熟,但合成其立体异构体的可靠和模块化方案仍然难以捉摸。在此,我们报告了通过实施链行走催化从易于获得的取代亚甲基环己烷模块化合成具有优异动力学立体控制的二取代环己烷的一般策略。从机制上讲,最初引入与环己烷相邻的空间要求高的硼酯基团是指导立体化学结果的关键。
