condensation of ortho-cyanomethylated nitroarenes with N-methylpyrrolidone, followed by cyclization promoted by O,N-bistrimethylsilylacetamide and DBU in DMF led directly to pyrrolo[3,2-b]quinoline derivatives.
邻位氰基甲基化硝基芳烃与 N-甲基吡咯烷酮的 Vilsmeier-Hack 缩合,然后在 DMF 中由 O,N-双三甲基甲硅烷基乙酰胺和 DBU 促进环化,直接导致吡咯并 [3,2-b] 喹啉衍生物。
