是一个值得注意的挑战,虽然大多数催化氢功能化方法通过1, 催化烯烃加氢功能化可以说是构建多种CX键并同时产生立体中心的最基本的重要方法之一, channelling hydrofunctionalization to 1,3-addition mode to create non-adjacent stereocentres with simultaneous controls of both relative and absolute configurations represents a notable challenge. Here we report a catalytic 1,随后引导催化剂在高区域化学和立体化学控制下对所得到的烯烃进行加氢功能化, subsequently directing the catalyst to hydrofunctionalize the resulting alkene with high regiochemical and stereochemical controls. The separate stereocontrols in this directing relay enables stereodivergent access to 1,3-hydroalkynylation products。
Bi-Jie IssueVolume: 2025-09-17 Abstract: Catalytic alkene hydrofunctionalization is arguably one of the most fundamentally important methodologies to construct diverse CX bonds with concomitant creation of stereogenic centres. While most catalytic hydrofunctionalization methodologies create a single stereocentre or vicinal stereocentres through 1,以同时控制相对和绝对构型,3-hydrofunctionalization of trisubstituted alkenes by a directing relay Author: Zhao。
