Multiple applications of isothioureas as fine chemicals (or their precursors) are known, but a general sustainable method for their synthesis was hitherto unavailable. We report a novel general approach towards S‐alkyl and S‐aryl isothioureas through a copper(I)‐catalyzed three‐component reaction between amines, isocyanides, and thiosulfonates. The formal synthesis of a superpotent sweetener further
异硫脲作为精细化学品(或其前体)的多种应用是已知的,但是迄今为止尚无通用的可持续合成方法。我们报告了一种通过胺,异氰化物和硫代磺酸盐之间的铜(I)催化的三组分反应对S-烷基和S-芳基异硫脲进行处理的新颖方法。高效甜味剂的形式合成进一步说明了我们方法的适用性。
