  Synthesis of optically active 3-substituted-10-alkyl-10H-phenothiazine-5-oxides by enantioselective biotransformations

  摘要：

  A series of racemic 10-alkyl-3-formyl-10H-phenothiazine-5-oxides (+/-)-2a-h were subjected to biotransformation with baker's yeast resulting in optically active aldehydes (+)-2a-h and alcohols (-)-3a-h in moderate enantiomeric excess. The racemic 10-alkyl-3-hydroxymethyl-10H-phenothiazine-5-oxides (+/-)-3a-h and 3-acetoxymethyl-10-alkyl-10H-phenothiazine-5-oxides (+/-)-4a-h obtained from the racemic aldehydes ()-2a-h were also tested in enantioselective lipase-catalyzed acetylations and alcoholysis reactions. The highest enantiomeric purities were achieved by a Novozyme 435-catalyzed acetylation-ethanolysis sequence, leading to optically active alcohols (-)-3a h in 83-92% e.e. A novel NMR method using enantiopure dibenzoyl tartaric acid as chiral additive was developed for determination of the enantiomeric composition of the optically active products.
