one‐pot cascade oxidative annulation reaction has been developed for the synthesis of [1,2,3]triazolo[1,5‐a]quinolines from methyl azaarenes and N‐tosylhydrazines. The reaction has a broad substrate scope and can be easily scaled up to gram‐scale. 1,2,3‐Triazoles are an important skeletal structure for the construction of C−C and C−P bonds, 2‐cyclopropylquinolines and imidazo[1,5‐a]quinolines, for which different
已经开发了一种碘促进的单锅级联氧化环化反应,用于从甲基氮杂芳烃和N-甲苯磺酰基肼合成[1,2,3]三唑并[1,5-α]喹啉。该反应具有广泛的底物范围,可以轻松放大至克级。1,2,3-三唑是构筑C-C和C-P键,2-环丙基喹啉和咪唑并[1,5-a]喹啉的重要骨架结构,已探索了它们的不同合成应用。
