Reaction Steps

4,6-Di-O-benzyl-3-O-tert-butyldimethylsilyl-D-glucal (3 mmol) was dissolved in THF (35 mL). Tetrabutyl fluoride (1M solution in THF) (3.5 mL) was added and the reaction mixture was stirred at room temperature overnight, then water (50 mL) was added and the mixture was extracted with ethyl acetate (3×50 mL). Combined organic extracts were washed with water until neutral, and dried over anhydrous sodium sulfate. Solids and solvents were removed and crude product was purified by column chromatography (SilicaGel 60) using hexanes:ethyl acetate as eluents. Pure 4,6-di-O-benzyl-D-glucal (2.61 mmol, yield 87%) was obtained. mp 53° C.
