An efficient approach for the synthesis of 4-amino-2-aryl-1,2,3-triazole derivatives has been developed through the copper-catalyzed direct C–H amination of 2-aryl-1,2,3-triazole N-oxides under mild reaction conditions. Various amines, including primary and secondary aliphatic and aromatic amines, can be employed as effective coupling partners. The general performance of our method was also demonstrated
通过铜催化的 2-芳基-1,2,3-三唑 N-直接 C-H 胺化,开发了一种合成 4-氨基-2-芳基-1,2,3-三唑衍生物的有效方法在温和的反应条件下生成氧化物。各种胺,包括脂肪族和芳香族伯胺和仲胺,都可以用作有效的偶联伙伴。噻唑和咪唑 N-氧化物的氧化胺化也证明了我们方法的一般性能。
