Résumé An efficient one-pot cross-coupling/1,3-dipolar cycloaddition sequence was developed for a convenient synthesis of 4,5-disubstituted-1,2,3-(NH)-triazoles, starting from various acid chlorides, terminal alkynes and sodium azide in the presence of silica supported-zinc bromide under aerobic conditions.
摘要 开发了一种高效的一锅法交叉偶联/1,3-双极环加成序列,用于便捷合成4,5-二取代-1,2,3-(NH)-三唑,起始原料为各种酸氯化物、末端炔烃和叠氮化钠,反应在空气条件下进行,使用硅胶支持的溴化锌。
