4H-3,1-Benzoxathiines from Benzothiete and Carbonyl Compounds The o-quinoid 8-π electron system 2, generated by thermal ring opening of benzothiete (1) undergoes [8π + 2π] cycloaddition reactions with electron-deficient carbonyl compounds 3. In accordance with the frontier orbital theory, 4H-3,1-benzoxathiines (4) are obtained in a regioselective manner.
