Utilization of Sugars in Organic Synthesis. Part XXV. Conversion of Thiocarbonyl into Carbonyl Group by O-S Exchange Reaction with Dibutyltin Oxide or Bistributyltin Oxide.
Cyclic thionocarbonates and thionolactones, when heated with 1.0-1.5 mol eq of dibutyltin oxide or bistributyltin oxide in dioxane, gave the corresponding carbonates and lactones in satisfactory yields, respectively.
