Abstract

β-Bromo-α, β-unsaturated electron withdrawing group containing dihydropyrrole nitroxides 2, 3, 4b, and 5b were used for synthesis of dihydropyrrol-1-yloxyl radicals annulated to thiazepine 7, 13 and thiophene 14a-g rings. The 4-bromo-3-formylsubstituted 2,5-dihydropyrrole 5b was also a synthon for the synthesis of 3,4-disubstituted nitroxides 17a-d, 18a-d, 19a- c, 20a-c.
