A palladium-catalyzed tandem cyclization-cross-coupling reaction using indolylborate as a transfer agent

Investigation of the palladium-catalyzed tandem cyclization-cross-coupling reaction using indolylborate (2) as a transfer agent has been carried out. Furthermore, the cross-coupling reaction performed under carbon monoxide led to the generation of indolyl ketones.

Indolylborate was successfully used for the palladium-catalyzed tandem cyclization-cross-coupling and cyclization-carbonylation-cross-coupling reactions.
