Reaction Conditions

Temperature	30 °C

Reaction Steps

Glucose 3 g, NADP 3 mg, toluene 0.25 ml, and (3S)-1-chloro-3-tert-butoxycarbonylamino-4-phenyl-2-butanone 2.5 g were added to 25 ml of a cultured medium of E. coli HB101 (pNTOM4G1) prepared in the same manner as in Example 7, and the mixture was stirred at 30° C. for 40 hr while adjusting to pH 6.5 by dropwise addition of 5 M sodium hydroxide. After completion of the reaction, the reaction mixture was extracted with toluene, desolvated and the extract was analyzed in the same manner as in Example 8. As a result, (2R,3S)-1-chloro-3-tert-butoxycarbonylamino-4-phenyl-2-butanol (yield 99.1%, diastereomeric excess 99.8% d.e.) was obtained.
