We report an iodine-catalyzed Povarov reaction using indole as dienophile carried out in toluene at room temperature. This three-component reaction, coupling an aldehyde, an amine, and an indole, proved to be an efficient method for synthesizing exo-indolo[3,2-c]quinoline derivatives related to the alkaloid isocryptolepine (cryptosanguinolentine) in good yield and with high stereoselectivity.
