A new method to efficiently prepare 3-substituted aryl[4,5]isothiazoles by simply heating the starting materials with a catalytic amount of p-toluenesulfonic acid in toluene is reported. This simple procedure is well suitable for a variety of substrates that can tolerate substitution changes in the fusing aromatic ring, as well as at the 3-position. Substituted aryl rings of varying electronic properties
报道了一种通过简单地加热原料与催化量的甲苯磺酸在甲苯中有效制备 3-取代芳基 [4,5] 异噻唑的新方法。这种简单的程序非常适用于可以容忍稠合芳环以及 3 位取代变化的各种底物。不同电子性质和烷基取代的取代芳环最终以高产率提供芳基[4,5]异噻唑。
