Microbiological reduction of ethyl benzoylacetate by bakers' yeast (Saccharomyces cerevisiae), Beauveria sulfurescens or Geotrichum candidum afforded ethyl (S)-3-hydroxy-3-phenylpropionate in high optical yield. This enantiomerically pure alcohol was converted into both enantiomers of fluoxetine (7). The product resulting from the bakers' yeast reduction had ee values (87–93%) lower than the 100% value
通过面包酵母(Saccharomyces cerevisiae),球孢白僵菌或白色念珠菌的微生物还原,可以高光学收率得到(S)-3-羟基-3-苯基丙酸乙酯。该对映体纯的醇被转化为氟西汀的两种对映体(7)。面包师减少酵母所产生的产品的ee值(87–93%)低于早期研究中错误归因于100%的值。
