The isothiourea-catalysed acylative kinetic resolution of a range of acyclic (±)-1,2-diols using 1 mol% of catalyst under operationally simple conditions is reported. Significantly, the bifunctional nature of (±)-1,2-diols was exploited in a sequential double kinetic resolution, in which both kinetic resolutions operate synergistically to provide access to highly enantioenriched products. The principles
报告了在操作简单的条件下使用 1 mol% 催化剂对一系列无环 (±)-1,2-二醇进行异硫脲催化的酰化动力学拆分。值得注意的是,(±)-1,2-二醇的双功能特性在连续双动力学拆分中得到了利用,其中两种动力学拆分协同运作以提供对高度对映体富集的产品的访问。讨论了支持该过程的原理,并在模型系统中报告了各个动力学拆分步骤的选择性因素。
