실험 절차

The reaction procedure of Example 9 was repeated except that 400 mg (1.27 mmols) of (2R,3R)-3-(benzyloxycarbonylamino)-4-phenylbutane-1,2-diol was used in lieu of 400 mg (1.27 mmols) of (2S,3S)-3-(benzyloxycarbonylamino)-4-phenylbutane-1,2-diol and the reaction product was purified by silica gel column chromatography (hexane/ethyl acetate=2/1) to provide (183 mg (0.887 mmol, yield 70%) of (4R,5R)-5-hydroxymethyl-4-phenylmethyloxazolidinone as crystals.
