New heterocyclic compounds, methyl 1,2-dihydroazuleno-pyrrole-9-carboxylate, its 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 isomers followed by demethoxycarbonylation, azulenopyrrole and azulenofuran are obtained, respectively.
