Single biotransformations of 1-(phenylthio)-2-propanone and 1-(p-methoxyphenylthio)-2-propanone by the fungus Helminthosporium species NRRL 4671 resulted in both sulfur oxidation to the sulfoxide and carbonyl reduction to the alcohol. The corresponding (SS,SC)-1-sulfinyl-2-propanols were obtained as single diastereomers following simple crystallization.Key words: biocatalysis, biotransformation, carbonyl
