실험 절차

((2S,4R)-4-(tert-butyldimethylsilyloxy)-6-oxotetrahydro-2H-pyran-2-yl)methyl acetate (VI) (0.625 g, 80% purity, 1.65 mmol) was dissolved in THF (8 mL) and MeOH (8 mL). Tin catalyst (tBu2SnClOH)2 (94 mg, 0.1 eq) was added and the reaction was stirred overnight. Reaction was concentrated and purified by flash chromatography to give pure (4R,6S)-4-(tert-butyldimethylsilyloxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-2-one (VII) (126 mg, 30%). VII was found to contain less than 0.1% of enantiomer.
