A new amide synthesis strategy based on a fundamental mechanistic revision of the reaction of thio acids and organic azides is presented. The data demonstrate that amines are not formed as intermediates in this reaction. Alternative mechanisms proceeding through a thiatriazoline intermediate are suggested. The reaction has been applied to the preparation of simple and architecturally complex amides
提出了一种基于硫代酸和有机叠氮化物反应的基本机理修正的新酰胺合成策略。数据表明在该反应中没有形成胺作为中间体。建议了通过噻三唑啉中间体进行的替代机制。该反应已用于制备使用常规方法难以获得的简单且结构复杂的酰胺。该反应具有化学选择性,对未受保护的底物有效,并与非质子和质子溶剂(包括水)相容。
