摘要:
To synthesize (R)-terbutaline hydrochloride, a potent beta(2)-adrenoceptor-stimulating agent, asymmetric reduction of a substituted alpha-chloroacetophenone derivative with cultured whole-cell biocatalyst of the yeast Williopsis californica JCM 3600 was developed as the key reaction. The reduction proceeded by a si-facial attack of hydride in a highly enantioselective manner. Co-factor generation was enhanced by applying glycerol as the carbon source. (C) 2012 Elsevier B.V.
