A yellow product formed in the reaction of 2,4-di-p-methylanilinocyclopent-2-enone with maleic anhydride has been shown by X-ray crystallographic analysis to be (4'-p-methylanilino-1'-p-methylophenyl-2',5'-dioxo-1',2',3',5',6',6'a-hexahydrocyclopentapyrrol-3'-yl)acetic acid (3) in accord with the spectroscopic data.Monoclinic crystals of (3) belong to the space group P21/n with a 13.399(2), b 8.386(1), c 17.935(3) Angstroem, β 92.06(2) deg and Z 4.Full-matrix refinement with 2292 observed data converged at R 0*063.
