Selective transformations of 2-(p-toluenesulfonyl)-N-tosylhydrazones with different sulfur sources have been established. A series of 4-aryl-1,2,3-thiadiazoles and novel 4-aryl-5-tosyl-1,2,3-thiadiazoles were selectively constructed by the adjustment of reaction conditions. These protocols feature short reaction time, good compatibility of functional group, easily available materials, and good selectivity.

2-（对甲苯磺酰基）-N-甲苯磺酰hydr选择性转化为取代的1,2,3-噻二唑

已经建立了具有不同硫源的2-（对甲苯磺酰基）-N-甲苯磺酰hydr的选择性转化。通过调节反应条件，选择性地构建了一系列的4-芳基-1,2,3-噻二唑和新型的4-芳基-5-甲苯基-1,2,3-噻二唑。这些协议的特点是反应时间短，官能团的相容性好，易于获得的材料和选择性好。
