New heterocyclic compounds, azuleno[1,2-b]- and azuleno[1,2-c]thiophene, are synthesized by the reaction of 3-methoxycarbonyl-2H-cyclohepta[b]furan-2-one with morpholino enamines of 3-oxotetrahydrothiophene, followed by dehydrogenation of resulting dihydrocompounds with 2,3-dichloro-5,6-dicyano-p-benzoquinone.
