A novel sulfur‐promoted cyclization of hydrazides and isonitriles to produce 1,3,4‐oxadiazole has been developed. The method is operationally simple and compatible with a wide scope of substrates and various 2‐amino‐ 1,3,4‐oxadiazoles are efficiently obtained in good yields.
已开发出一种新的硫促进的酰肼和异腈环化反应以生产1,3,4-恶二唑。该方法操作简单,可与多种底物兼容,可以高效获得各种2-氨基-1,3,4-恶二唑。
