A general and efficient method for the synthesis of S-substituted 5-sulfanylmethyl(ethyl)-1,3,4-thiadiazol-2-amines via cyclocondensation of aryl(benzyl)sulfanylacetic and -propionic acids with thiosemicarbazide upon their heating in POCl3 was developed. Both aryl- and benzylsulfanilacetic and -propionic acids were successfully involved in this reaction to give the target thidiazolamines in high yields
一种通过芳基(苄基)硫烷基乙酸和-丙酸与氨基硫脲在 POCl 3中加热环缩合合成 S-取代的 5-硫烷基甲基(乙基)-1,3,4-噻二唑-2-胺的通用有效方法发展了。芳基和苄基磺胺乙酸和丙酸都成功地参与了该反应,以高产率(63-98%)得到目标噻二唑胺。
