Deracernization of (+/-)-3-hydroxy-4-chrornan one 2 through stercoselective bioreduction to the corresponding (3R,4S)-3,4-chromanediol 3, with good to excellent enantiomeric excesses (LIP to 99%). mediated by resting cells of the yeast Trichosporon cutaneum CCT 1903, is reported. In addition, 3-hydroxychronione (7) was obtained as a secondary product. (c) 2005 Elsevier Ltd. All rights reserved.
