One‐pot synthesis of heterocycle fused‐triazole analogs from the corresponding aldehydes and heteroarylhydrazines is demonstrated. Transformation of hydrazones to the desired systems was achieved by employing the oxidative cyclization with catalytic CuBr2 and oxone. This reaction condition is mild and selective, and a wide range of functional groups were able to sustain. An array of biologically important
证明了从相应的醛和杂芳基肼一锅法合成杂环稠合三唑类似物。通过使用催化性的CuBr 2和氧杂环丁烷进行氧化环化,可将转化为所需的系统。该反应条件温和且选择性,并且能够维持多种官能团。以相当高的产率获得了一系列生物学上重要的三唑并吡啶,三唑并哒嗪,三唑并嘧啶和三唑并喹啉。
