An efficient method for the preparation of 1,4-disubstituted 1,2,3-triazole compounds is described using polymeric quaternary ammonium salts having azide or alkyne functionality to remove unreacted excess starting molecules (azide/alkyne). Copper metal could easily be removed by simple filtration with a short Na 2 SO 4 /silica cartridge, affording highly regioselective products in high yield and excellent
描述了一种制备 1,4-二取代 1,2,3-三唑化合物的有效方法,该方法使用具有叠氮化物或炔烃官能团的聚合季铵盐去除未反应的过量起始分子(叠氮化物/炔烃)。使用短的 Na 2 SO 4 /硅胶柱可以通过简单的过滤轻松去除铜金属,无需后处理、萃取和色谱纯化即可获得高产率和高纯度的高区域选择性产品。
