A New Synthesis of Naphthopyrroles. Conversion of Naphthothiophene-4,9-diones to Naphthopyrrole-4,9-diones.

A series of 2-substituted-4,9-dihydronaphthopyrrole-4,9-diones was prepared by the reaction of 4,9-dihydronaphthothiophene-4,9-diones with primary amines under mild conditions.The presence of halogen in the naphthothiophene-4,9-dione and the presence of hydroxyl, ether, or tertiary amine functions in the amine reagent do not interfere with the course of the reaction.
