摘要

在Pd(OAc)2的催化下，Ullmann偶联和氧化偶联脱氢反应先后发生，意外地产生了高收率的咪唑[1,2-f]菲咯啉衍生物。中间产物和最终产物的结构分析表明，该方案不包括C-H和N-H基化。

Pd(OAc)2-Catalyzed Synthesis of Imidazo[1,2-f]phenanthridines via a Sequential Ullmann Coupling and Oxidative Coupling Dehydrogenation

The Ullmann coupling and oxidative coupling dehydrogenation reactions have occurred sequentially, catalyzed by Pd(OAc)₂, which unexpectedly yielded fused imidazo[1,2-f]phenanthridine derivatives in good to high yields. Structural analysis of the intermediate and final products indicated that the protocol did not include C–H and N–H arylation.
