An efficient method for the synthesis of N‐alkylated 2‐(4‐substituted‐1H‐1,2,3‐triazol‐1‐yl)‐1H‐indole‐3‐carbaldehyde has been developed starting from oxindole and indole using Huisgen's 1,3‐dipolar cycloaddition reaction of organic azides to alkynes. The effect of catalysts and solvent on these reactions has been investigated. Among all these conditions, while using CuSO4·5H2O, DMF was found to be
从吲哚和吲哚开始,已开发出一种高效的合成N-烷基化2-(4-取代1 H -1,2,3-三唑-1-基)-1 H-吲哚-3-甲醛的方法。惠斯根有机叠氮化物与炔烃的1,3-偶极环加成反应。已经研究了催化剂和溶剂对这些反应的影响。在所有这些条件中,使用CuSO 4 ·5H 2 O时,发现DMF是该反应的最佳系统。也可以通过处理等摩尔量的卤化物,叠氮化物和炔烃,以一锅三组分的方式制备。Huisgen的1,3-偶极环加成反应是使用CuSO 4 ·5H 2进行的DMF中的O,操作过程简单。
