Abstract
The 7-oxa-2,3-dimethylenenorbornene derivative (3), synthesized previo usly from 4H,6H-thieno[3,4-c]furan 5,5-dioxide (1) through its 2-acyla ted derivative (2), reacted with a variety of dienophiles to give the adducts (4), the functionalized tetracyclic compounds, in good to exce llent yield.
