A new, efficient method for the preparation of 1,2,4-oxadiazoles from N-benzoylamidino compounds by treatment with t-butyl hypochlorite and sodium hydroxide has been devised. It was supposed that the ring formation proceeds via a nitrene intermediate.
设计了一种新的、有效的方法,通过用次氯酸叔丁酯和氢氧化钠处理,从 N-苯甲酰脒基化合物制备 1,2,4-恶二唑。据推测,环的形成是通过氮烯中间体进行的。
