Diverse thiol esters were synthesized in good to excellent yields (76-99%) by reactions of thiophenol, benzyl mercaptan, ethyl mercaptoacetate, and mercaptoacetic acid with N-acylbenzotriazoles under mild conditions. These results demonstrate the utility of N-acylbenzotriazoles as mild S-acylating agents, especially when the corresponding acid chlorides are not readily available.
通过苯硫酚、苄硫醇、巯基乙酸乙酯和巯基乙酸与 N-酰基苯并三唑在温和条件下反应,以良好至优异的产率 (76-99%) 合成了多种硫羟酸酯。这些结果证明了 N-酰基苯并三唑作为温和的 S-酰化剂的效用,尤其是当相应的酰氯不易获得时。
