A series of 6H-isoindolo[2,1-a]indol-6-ones were synthesized through one-pot sequential coupling reactions, which were comprised of a copper-catalyzed C–N coupling cyclization and a palladium-catalyzedC–Hactivation course. General chemicals benzoyl chlorides and o-gem-dibromovinyl anilines were employed as the starting substrates.

Tandem palladium-catalyzed N,C-coupling/carbonylation, under 10 atm of carbon monoxide and at 110 degrees C, is a novel and efficient method for the preparation of 2-carboxyindoles. The catalyst system tolerates a variety of functional groups, and the noted indoles were obtained in good isolated yields.
