Furan-fused 3-sulfolene as a novel building block: Intermolecular Diels-Alder reactions of 4H,6H-thieno[3,4-c]furan 5,5-dioxide

A furan-fused 3-sulfolene 4H,6H-thieno[3,4-c]furan 5,5-dioxide 1, can be used as a bis-diene, reacting sequentially with a variety of dienophiles to construct four types of skeleton, depending on the dienophile and the reaction conditions. The 3-sulfolene

Novel Building Block, Furan-annelated 3-Sulpholene; Diels-Alder Reactions of 4,6-Dihydrothienofuran S,S-Dioxide

The preparation of the hitherto unknown 4,6-dihydrothienofuran S,S-dioxide 1 and its intermolecular Diels-Alder reactions with typical dienophiles are described.
