A novel reaction of propargylamines with aryl azides is designed for the synthesis of 5-amino-1,2,3-triazoles employing a one-pot strategy. In this process, base-mediated isomerization of propargylamines generates allenamine intermediates, which participate in a cyclization reaction with azides. Optimization of the reaction conditions revealed that t-BuOK as the base and DMF as the solvent gave the
设计了一种炔丙基胺与芳基叠氮化物的新型反应,用于采用一锅法合成 5-氨基-1,2,3-三唑。在这个过程中,炔丙基胺的碱介导异构化生成丙二胺中间体,该中间体参与与叠氮化物的环化反应。反应条件的优化表明t -BuOK作为碱和DMF作为溶剂得到最好的收率。该协议扩展到不同的炔丙基胺和叠氮化物,结果表明 3-芳基炔丙基胺和芳基叠氮化物可以产生相应的 1,2,3-三唑。该程序提供了一种简单有效的方法来获得一系列具有广泛官能团的 5-氨基-1,2,3-三唑。
