Enantiopure (-)-trans-benzo[d]dithiine-S,S′-dioxide 4 was obtained by enantioselective oxidation of the parent benzo[d]dithiine. The reaction of the bis-sulfoxide with a series of cyclic dienes affords the corresponding Diels-Alder cycloadducts with diastereoselectivities ranging from fair to high and good chemical yields.

1,4-Benzodithiin 1,1,4,4,-tetraoxide undergoes the Diels-Alder reaction with a series of dienes under mild condition to provide the corresponding adducts in excellent yields.The adduct with anthracene is desulfonated to afford dibenzobarrelene, thus showi
