  Microbial reduction of 1-tetralone 2-carboxyesters as a source of new asymmetric synthons

  摘要：

  The reduction of unsubstituted or methoxy-substituted (+/-)-2-carboxyethyl-1-tetralones by selected microorganisms affords optically active 1-hydroxy-2-carboxyethyl tetralins which can be used as versatile asymmetric synthons, for example in the preparation of biologically active methoxy-substituted 2R-aminotetralins. 1R,2R-(cis)-hydroxyesters of high optical purity are obtained with yeast strains, while the use of filamentous fungi leads to the enantiomeric 1S,2S-(cis)-hydroxyesters.
