실험 절차

(3R,3aS,6aR)-Hexahydrofuro[2,3-b]furan-3-yl acetate (II, 14.0 g) was dissolved in methanol (42 mL). Potassium carbonate (0.34 g) was added and stirred at 25-35° C. for 6-8 hours. Methanol Was distilled out completely under vacuum, to the distillate methylenedichloride (28 mL) was added, stirred the mass for 30 minutes and again distilled the solvent to get residue. Dissolved the residue in dichloromethane (56 mL), the resultant solution was treated with carbon and the solvent was completely distilled out get title compound I (yield 10.5 g).
