摘要/Abstract

动力学拆分是获得手性化合物的最常用方法之一. 在过去的二十年里, 氮杂环卡宾催化的动力学拆分得到了快速的发展, 作者曾在2017年发表的综述文章中进行了一次总结. 自此以后, 该领域取得了一系列新的研究进展, 将阐述这一研究领域自2017年年中至2023年的最新研究进展.

关键词: 动力学拆分, 氮杂环卡宾, 不对称催化, 消旋体, 对映体富集化合物

Kinetic resolution is one of the most commonly used methods allowing access to enantioenriched compounds. The last two decades have seen the rapid development of kinetic resolutions enabled by N-heterocyclic carbene catalysis, and part of the achievements have been summarized in our previous review paper published in 2017. Since then, a series of new advances have been realized, and this review will provide an update of this field covering reports from mid-2017 to 2023.

Key words: kinetic resolution, N-heterocyclic carbene, asymmetric catalysis, racemates, enantioenriched compounds
