The 1,4-cycloaddition of different N-arylmaleimides (IIa-f) to alkylidene- and arylidene-fluorenones (Ia-c) leads to the formation of the diadducts, 7-substituted-5-aryl-4,6-dioxo-4H-3,3a,5,6,6a,7,10b-octahydrofluoranthenopyrrole-endo(3,10b)-N-arylpyrrolidino-2',5'-diones (IIIa-r).The fully aromatized fluoranthene derivatives (Va-i) have also been synthesised either by boiling III in nitrobenzene or by reacting the bromo-derivatives (V) with appropriate II.Reduction of III using LAH gives VIII.The structures of the isolated products have been confirmed by elemental analyses, molecular weight determination and spectroscopic data.
