摘　　要：四氮杂䓬衍生物具有良好的生物活性, 目前, 对于该骨架的构建方法非常有限, 因此, 建立了一种通过氢氧化钾促进α-卤代乙酰腙原位形成1,2-氮杂二烯中间体, 与偶氮次甲基亚胺环合反应合成高度取代的四氮杂䓬衍生物的新方法. 该方法表现出良好的官能团耐受性和底物普适性.Tetrazepine derivative exhibits good biological activities. Only a limited method has been devoted to constructing these frameworks to date. Therefore, an efficient and novel way was established for the synthesis of functionalized tetrazepine scaffolds through the cycloaddition reaction of azomethine imine with 1,2-azadiene formed in situ by α-halogeno hydrazones in the presence of KOH. This transformation shows excellent functional group tolerance and substrate scope.
