Reaction Steps

(1R*,4R*,5R*)-4-Iodo-6-oxabicyclo[3.2.1]octan-7-one (J. Org. Chem., 1996, Vol. 61, p. 8687) (14.3 g) was dissolved in ethanol (130 ml), a 2N aqueous solution (34.5 ml) of sodium hydroxide was added under ice cooling, and the mixture was then stirred at room temperature for 7 hours. After the solvent was distilled off under reduced pressure, and water was added to the residue to conduct extraction with dichloromethane, the extract was dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by column chromatography on silica gel (hexane:ethyl acetate=83:17) to obtain the title compound (6.54 g) as a colorless oil.
