A novel strategy towards the synthesis of 1,4-disubstituted 1,2,3-triazoles via C–N and N–N bond formation has been demonstrated under transition metal-free and azide-free conditions. These 1,2,3-triazoles were obtained in a regioselective manner from commercially available anilines, aryl alkenes/aryl alkynes and N-tosylhydrazines using I2 under O2 atmosphere. Broad substrate scope, milder reaction
在无过渡金属和无叠氮化物的条件下,已经证明了一种通过C-N 和 N-N 键形成合成 1,4-二取代 1,2,3-三唑的新策略。这些1,2,3-三唑是在O 2气氛下使用I 2从市售苯胺、芳基烯烃/芳基炔烃和N-甲苯磺酰肼以区域选择性方式获得的。广泛的底物范围、较温和的反应条件、良好至中等的产率和清洁方案是该方法的显着特点。此外,该协议适用于生成医学上重要的关键构建块库。
