Stereoselectivity of Yeast Reductions - an Improved Procedure for the Preparation of Ethyl (S)-3-Hydroxybutanoate and (S)-2-Hydroxymethylbutanoate

Ethyl 3-oxo- and 2-formyl-butanoate (4-5 g/L) are reduced in ca. 70% yield to the title compounds of > 90% enantiomeric excess by baker’s yeast (125 g/L) which had been kept in 5 % aqueous ethanol with shaking under aerobic conditions in the absence of sugar for four days.
