Diazotization of the 3-aminopyrrole-4-carboxamides 6a,b under different conditions directly led to the new ring system pyrrolo[3,4-d]-1,2,3-triazine in excellent yields through an intramolecular coupling reaction. In all the cases it was impossible to isolate the intermediate 3-diazopyrroles.
3-氨基吡咯-4-羧酰胺6a,b在不同条件下的重氮化直接导致新的环系统吡咯并[3,4- d ] -1,2,3-三嗪通过分子内偶联反应以优异的产率产生。在所有情况下,都不可能分离出中间体3-重氮吡咯。
