Abstract
Seven fungi, which are found to reduce ethyl 3-oxobutanoate in high yields, were tested for their reducing ability for ethyl 2-methyl 3-oxobutanoate. We obtained some interesting findings. In particular, Penicillium purpuroge num reduced ethyl 2-methyl 3-oxobutanoate to the corresponding alcohols wit h the diastereomer (anti/syn) ratio of 93/7 with the enantiomeric excess of anti-(2S,3S)- and syn-(2S,3R)-hydroxy esters of 90 and >99 ee%, respective ly.
