Screening of yeast species for the stereo-selective reduction of bicyclo[2.2.2]octane-2,6-dione
No full textYeast strains from more than 31 different genera were screened for the enantioselective reduction of bicyclo[2.2.2]-octane-2,6-dione (1). Reducing activity was found in 80% of the screened yeasts. Bicyclo[2.2.2]octane-2,6-dione was enantioselectively reduced (> 98% ee) to (1R, 4S, 6S)-6-hydroxybicyclo[2.2.2]octane-2-one (-)-2 by 69% of the strains. Enantioselective reduction of the diketone to (1S, 4R, 6S)-6-hydroxybicyclo[2.2.2]octane-2-one ((+)-3, >98% ee) as a major product is reported for the first time. Candida tropicalis UOFS Y-0534 and Candida wickerhamii UOFS Y-0652 displayed this unusual diastereoselectivity
