In summary, we have demonstrated an efficient and facile synth-
esis of pyrrolo[3,2-c]quinolines (the core nucleus of the natural
product martinellic acid) via selective formation of pyrrole inter-
mediates over indoles starting from easily accessible 2-(4-aminobut-
1-yn-1-yl)anilines. The structures of the intermediates and final
products were confirmed using X-ray crystallographic analysis. The
regioselectively cyclized product 5 embedded with an iodo handle
could be used for further elaboration using palladium-catalyzed
coupling reactions. From a synthetic point of view the developed
strategy is simple and general, and can be used for the construction of
