Article abstract of DOI:10.3987/R-1987-07-1785

Acid-catalyzed intramolecular aldol condensation of diketo sulfides generally affords 2,6-dihydrothiopyran-3-ones and/or their 2,4-dihydro isomers in good yields.The ketol intermediates, in a few cases, undergo sulfur-participated rearrangement to give th
