Abstract
Reactions of thiophene dioxides containing electron-withdrawing substituents with furans were studied. The reactions with unsubstituted furan followed the inverse-electron-demand Diels-Alder mechanism. Subsequent elimination of sulfur dioxide from the adduct afforded products of the tetrahydrobenzofuran series. The reactions with substituted furans gave benzylcarbonyl compounds in high yields. The observed regiochemistry of the reaction was explained in terms of the frontier orbital theory using the calculated orbital coefficients.
