A multicomponent (single reactor) process for the synthesis of 1-aryl 1,2,4-triazoles was explored and developed. This transformation prepared the 1,2,4-triazole directly from anilines, amino pyridines, and pyrimidines. The reaction scope was explored with 21 different substrates, and the position of the nitrogen atoms in the newly formed ring was established by 15N labeling and NMR spectroscopy.
探索和开发了一种用于合成1-芳基1,2,4-三唑的多组分(单反应器)工艺。该转化直接从苯胺,氨基吡啶和嘧啶制备1,2,4-三唑。用21种不同的底物探索了反应范围,并通过15 N标记和NMR光谱确定了新形成的环中氮原子的位置。
