Under thermal extrusion of SO2, ethyl 3,5-dihydro-4,4-dioxo-1H-thieno[3,4-c]pyrrole-2-carboxylates was cycloadded to C60 to give [60]fullerocyclohexane-fused pyrrole-2-carboxylates. While the reaction with N-substituted pyrroles afforded relatively soluble cycloadducts, the isolated solid product from the N-unsubstituted one was found to be not readily soluble. Nevertheless, its structure was confirmed by Boc-protection of the primarily formed cycloadduct.
