Abstract: The synthesis of 2-(2-nitrophenyl)-, 2-(4-chloro-2-methylphenoxy)furo[3,2-b]pyrroles, and their TV-substituted derivatives, as well as the prepara­ tion of l,2-dihydropyrrolo[2',3: 4,5]furo[3,2-b]indole is described. Reac­tions of prepared compounds with dimethyl butynedioate were investigated. It was found that the reaction course is influenced by substituents attached to the furo[3,2-b]pyrrole system. Products of [4 + 2] cycloaddition as well as products of Michael addition were obtained.
