(S)-(+)-1-Phenyl-2,2,2-trifluoroethanol

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To 20 ml of 50 mM potassium dihydrogenphosphate-dipotassium hydrogenphosphate buffer (pH 7.0) are added 1 g of the washed bacterial bodies prepared in Example 7, 12 mg of NAD+ and 2.5 g of glucose. After adding 240 mg of 2,2,2-trifluoroacetophenone to this mixture, the pH of this mixture is adjusted to 7.0 with a 15% aqueous sodium carbonate solution. The reaction is executed by stirring thus obtained mixture (reaction mixture) at 30° C. for 4 hours. After completion of the reaction, 25 ml of ethyl acetate is poured into the reaction mixture and stirred, followed by centrifugal separation for separately collecting the organic phase and the aqueous phase. To the collected aqueous phase is added 25 ml of ethyl acetate again, and the similar operation is repeated. After concentrating the combined organic phase obtained in such a manner, the concentrate is dissolved in 30 ml of chloroform and dried using anhydrous Na2SO4. After drying, chloroform is distilled off to obtain (S)-2,2,2-trifluoro-1-phenylethanol. mixture (reaction mixture) at 30° C. for 4 hours is poured into the reaction mixture stirred followed by centrifugal separation for separately collecting the organic phase To the collected aqueous phase is added 25 ml of ethyl acetate again After concentrating the combined organic phase obtained in such a manner dried After drying chloroform is distilled off
