Alkylation of 4H,6H-Thienofuran 5,5-Dioxide and Its Use as a 3,4-Dimethylenefuran Synthon in Intramolecular Diels-Alder Reactions

4H,6H-thienofuran 5,5-dioxide 1 was readily converted to the 4-alkylated compounds 2 and the appropriate compounds 2 were submitted to intramolecular Diels-Alder reactions to afford fused furans 8a and b in good yields.

Alkylation of 4H,6H-Thienofuran 5,5-Dioxide and Its Use as a 3,4-Dimethylenefuran Synthon in Intramolecular Diels-Alder Reaction

Alkylation of 4H,6H-thienofuran 5,5-dioxide (furan-annulated sulfolene) 1 readily gave its 4-alkyl, 4,6-dialkyl, or 4,4-dialkyl derivatives, selectively.Attempts were made to use the appropriate derivatives as 3,4-dimethylenefuran synthons in intra
