represents a Cu-catalyzed three-component reaction between readily available 5-iodo-1,2,3-triazoles, amines, and CS2. The cascade transformation is based on a denitrogenative coupling of in situ formed dithiocarbamic acids with diazo intermediates, generated via annulation-triggered triazole ring-opening. This method is applicable to nucleophilic secondary amines and features good functional group compatibility
已经开发了一种有效的多米诺骨牌方法来组装带有二硫代氨基甲酸酯部分的苯并恶唑和邻氨基苯甲酰胺。所提出的路线代表了容易获得的 5-iodo-1,2,3-triazoles、胺和 CS 2之间的 Cu 催化的三组分反应。级联转化基于原位形成的二硫代氨基甲酸与重氮中间体的脱氮偶联,通过环化触发的三唑开环产生。该方法适用于亲核仲胺,具有良好的官能团相容性。
