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
(±)-2-羟基-1-四氢萘酮(6)的对映体和对映体选择性还原为相应的对映纯(1 S,2 R)-顺式-1,2-二羟基-1,2,3,4-四氢萘(1)(83%的分离产率,> 99%ee),通过动态动力学拆分被报道了由酵母Trichosporon cutaneum CCT 1903的静止细胞介导。在动力学研究中,对映体(R)-6和(S)-6的生物转化过程中观察到(±)-6的脱轨。
