NADP nicotinamide-adenine-dinucleotide phosphate → 1,1-Dimethylethyl N-[(1S,2R)-3-chloro-2-hydroxy-1-(phenylmethyl)propyl]carbamate

温度

30 °C

Glucose 6 g, NADP 1.4 mg, toluene 0.25 ml, and (3S)-1-chloro-3-tert-butoxycarbonylamino-4-phenyl-2-butanone 2.5 g were added to 50 ml of a cultured medium of E. coli HB101 (pNTOM5G1) prepared in the same manner as in Example 7, and the mixture was stirred at 30° C. while adjusting to pH 6.5 by dropwise addition of 5 M sodium hydroxide. One hour after the start of the reaction, 2.5 g of (3S)-1-chloro-3-tert-butoxycarbonylamino-4-phenyl-2-butanone was added, and the mixture was reacted for 20 hr. 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 99.6%, diastereomeric excess 99.8% d.e.) was obtained.
