A novel approach to functionalized polycyclic systems; Synthesis of tetracyclic compounds by sequential rearrangement-cycloaddition reactions of 7-oxa-2,3-dimethylenenorbornene derivative

The tricyclic diene (6), readily accessible from a novel building block, 4H, 6H-thieno[3,4-c]furan 5,5-dioxide (1), reacted with a variety of dienophiles to give the tetracyclic perhydroazulene derivatives (7) in good to high yield.
