acetic acid-promoted approach that enables the synthesis of 1,4,5-trisubstituted 1,2,3-triazole derivatives has been achieved. This transformation employs readily available primary amines, 1,3-dicarbonyls and tosyl azide as the starting materials via a cycloaddition reaction under metal-free conditions. The reaction provides a simple access to fully substituted 1,2,3-triazoles from commercial substrates
已经实现了乙酸促进的方法,该方法能够合成1,4,5-三取代的1,2,3-三唑衍生物。该转化通过在无金属条件下的环加成反应,使用容易获得的伯胺,1,3-二羰基和甲苯磺酰基叠氮化物作为起始原料。该反应提供了从商业底物以中等到优异的产率简单地获得完全取代的1,2,3-三唑的方法。
