Abstract The synthesis of fused [5,5]‐1,2,4‐triazoles via a tandem cyclopropane rearrangement–cyclization sequence is described. Optimization of the cyclization reaction was achieved thermally using iPrOH as the solvent in the presence of TEA. This method was applied to the preparation of 3‐substituted‐7‐aryl‐pyrrolo‐1,2,4‐triazoles in good to excellent yields.
摘要描述了通过串联环丙烷重排-环化序列合成稠合 [5,5]-1,2,4-三唑。环化反应的优化是在 TEA 存在下使用 iPrOH 作为溶剂实现的。该方法用于制备 3-取代-7-芳基-吡咯并-1,2,4-三唑,收率良好。
