A novel, efficient and mild KHSO4 mediated synthesis for 2-amino-1,3,4-oxadiazoles has been established via the cyclodesulfurization of benzoylhydrazine and isothiocyanate derivatives in one pot. The reactions proceeded smoothly at room temperature and produced corresponding products in moderate to good yields. This protocol also showed good functional group tolerance.
通过苯甲酰肼和异硫氰酸酯衍生物的环化脱硫,建立了一种新型、高效且温和的 KHSO 4介导的 2-氨基-1,3,4-恶二唑合成方法。反应在室温下顺利进行,并以中等至良好的收率产生相应的产物。该协议还显示出良好的官能团耐受性。
