  名称：

  Hydrolase-catalyzed preparation of (R)- and (S)-4-hydroxy-2,6,6-trimethyl-2-cyclohexen-1-ones (phorenols), the key synthetic intermediates for abscisic acid

  摘要：

  Preparation of both the enantiomers of 4-hydroxy-2,6,6-trimethyl-2-cyclohexen-1-one (phorenol), which are versatile synthetic intermediates for abscisic acid and carotenoids, was achieved by hydrolase-catalyzed hydrolysis of the corresponding chloroacetate. The hydrolysis with esterase SNSM-87 (Nagase) enriched the (S)-ester, while lipase P (Amano) afforded the (R)-ester. (C) 1999 Elsevier Science Ltd. All rights reserved.
