The synthesis of 1-monosubstituted 1,2,3-triazoles was achieved using azides and propiolic acid by copper-catalyzed click cycloaddition/decarboxylation, which was easily carried out in N,N-dimethylformamide at room temperature or 60 ˚C with yields ranging from moderate to excellent. The reaction conditions were found to be successful for aryl and vinyl azide reactants, including analogues with various
通过铜催化的点击环加成/脱羧反应,使用叠氮化物和丙酸完成了1-单取代的1,2,3-三唑的合成,该反应很容易在室温,60°C的N,N-二甲基甲酰胺中进行,收率范围为从中等到优秀。发现该反应条件对于芳基和叠氮化乙烯反应物是成功的,包括具有各种功能的类似物。 点击化学-铜催化-脱羧-杂环-1-单取代1,2,3-三唑
