| Abstract: | The biotransformations of a series of substituted sulfides were carried out with the filamentous fungi Botrytis cinerea, Eutypa lata and Trichoderma viride. Several products underwent microbial oxidation of sulfide to sulfoxide with medium to high enantiomeric purity. With regard to sulfoxide enantioselectivity, the (R)-enantiomer was favoured in biotransformations by T. viride and E. lata while the (S)-enantiomer was favoured in those by B. cinerea. A minor amount of sulfone product was also obtained. |
