A convenient synthesis of indeno[1,2-c]isoquinoline-5,11-diones has been achieved using combinational photochemical and carbocationic cyclization tactics. The synthetic route involved first the construction of adequately functionalized N-styryl benzamides via Suzuki-Miyaura cross-coupling reaction with enol phosphate combined with a six-p-electron photocyclization process. The assembling of the title compounds was readily ensured through sequential carbocationic annulation reaction and ultimate oxidation of a latent hydroxy functionality.
