A facile and efficient protocol for the synthesis of 4-substituted-1H-[1,2,3]triazolo[4,5-c]quinolines through a CuO-promoted tandem cyclization reaction has been developed. This method allows for the construction of two heterocyclic rings in a one-pot reaction of readily available (E)-3-(2-bromoaryl)-1-arylprop-2-en-1-ones and sodium azide without the addition of any additive. A series of triazole-fused
已经开发了一种通过 CuO 促进的串联环化反应合成 4-取代-1H-[1,2,3] 三唑并 [4,5-c] 喹啉的简便有效的方案。该方法允许在容易获得的 (E)-3-(2-溴芳基)-1-芳基丙基-2-en-1-ones 和叠氮化钠的一锅反应中构建两个杂环,而无需添加任何添加剂。可以以中等至良好的产率制备一系列三唑稠合的 N-杂环化合物。
