Abstract The iodine-catalyzed reaction of 2-aminobenzamide and 2-oxopentanedioic acid in ionic liquids is described in this paper. It gave 1,5-dioxo-1,2,3,3 a ,4,5-hexahydropyrrolo[1,2- a ]quinazoline-3 a -carboxylic acid derivatives in high yields. One of their structures was confirmed by X-ray diffraction analysis.
