New heterocyclic compounds, methyl 1,2-dihydroazuleno<1,2-b>-pyrrole-9-carboxylate, its <1,2-c> isomer, and the furan analogues are synthesized by the reaction of 3-methoxycarbonyl-2H-cyclohepta-furan-2-one with morpholino enamines of N-ethoxycarbonyl-3-oxopyrrolidine or 3-oxotetrahydrofuran.By the dehydrogenation of the resulting <1,2-b> isomers followed by demethoxycarbonylation, azuleno<1,2-b>pyrrole and azuleno<1,2-b>furan are obtained, respectively.
