The diastereo- and enantioselective bioreduction of (+/-)-2-hydroxy-1-tetralone (6) to the corresponding enantiopure (1S,2R)-cis-1,2-dihydroxy-1,2,3,4-tetrahydronaphthalene (1) (83 % isolated yield, > 99 % ee), mediated by resting cells of the yeast Trichosporon cutaneum CCT 1903 through dynamic kinetic resolution is reported. Deracemization of (+/-)-6 was observed in kinetic studies on the biotransformation of the enantiomers (R)-6 and (S)-6.3496925932
