  Enantioselective α-Hydroxylation of 2-Arylacetic Acid Derivatives and Buspirone Catalyzed by Engineered Cytochrome P450 BM-3

  摘要：

  Here we report that an engineered microbial cytochrome P450 BM-3 (CYP102A subfamily) efficiently catalyzes the alpha-hydroxylation of phenylacetic acid esters. This P450 BM-3 variant also produces the authentic human metabolite of buspirone, R-6-hydroxybuspirone, with 99.5% ee.

  buspirone. The (R)- and (S)-enantiomers of 6-hydroxybuspirone were prepared using an enzymatic resolution process. l-Amino acid acylase from Aspergillus melleus (Amano Acylase 30000) was used to hydrolyze racemic 6-acetoxybuspirone to (S)-6-hydroxybuspirone in 95% ee after 45% conversion. The remaining (R)-6-acetoxybuspirone with 88% ee was converted to (R)-6-hydroxybuspirone by acid hydrolysis. The
