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.
新型杂环化合物,蓝烯[1,2-b]和蓝烯[1,2-c]硫烯,通过3-甲氧基羧基-2H-环庚[b]呋喃-2-酮与3-氧代四氢噻吩的莫非林烯胺反应合成,随后将所得的二氢化合物用2,3-二氯-5,6-二氰基-p-苯醌进行脱氢处理。
