Pyrrolo[2,1-f][1,2,4]triazin-4(3H)-ones 12 have been easily prepared via nucleophile-induced rearrangement of pyrrolooxadiazines 11 and regioselective intramolecular cyclization of 1,2-biscarbamoyl-substituted 1H-pyrroles 10. In this work, we demonstrated that the described synthetic approaches can be considered to be more facile and practical than previously reported procedures.
吡咯并[2,1-f] [1,2,4]三嗪-4(3H)-一很容易通过亲核试剂诱导的吡咯并恶二嗪11的重排和1,2-双氨基甲酰基取代的1H-的区域选择性分子内环化反应制备吡咯10.在这项工作中,我们证明了所描述的合成方法比以前报道的方法更容易和实用。
