実験手順
To a solution of tert-butyl[(2R,35)-5-methylene-2-(2,4,5-trifluorophenyl)tetrahydro-2H-pyran-3-yl]carbamate (203 mg, 0.59 mmol) in tert-butyl alcohol (6 mL), acetone (3 mL) and water (1.5 mL) was added osmium tetroxide (0.113 mL of 2.5% solution in tert-butyl alcohol, 0.009 mmol). The resultant mixture was stirred at room temperature for 10 minutes and then treated with N-methylmorpholine N-oxide (92 mg, 0.79 mmol) and stirred. After two days, the reaction mixture was treated with aqueous sodium bisulfate solution (5 mL, 2.0N) followed after 10 min by ethyl acetate. The organic layer was washed successively with 2N hydrochloric acid and saturated aqueous sodium bicarbonate solution, dried over anhydrous sodium sulfate, filtered and evaporated to yield tert-butyl [(2R,3S)-5-hydroxy-5-(hydroxymethyl)-2-(2,4,5-trifluorophenyl)tetrahydro-2H-pyran-3-yl]carbamate which was used in the next step without further purification.
