  Enzyme-mediated synthesis of EEHP and EMHP, useful pharmaceutical intermediates of PPAR agonists

  摘要：

  A new scaleable synthetic route to the title compounds has been developed. The reaction pathway is based on the alpha-chymotrypsin-catalysed hydrolysis of the racemic ethyl 2-ethoxy-3-(p-methoxyphenyl)propanoate or of the racemic ethyl 2-methoxy-3-(p-methoxyphenyl)propanoate to give the corresponding resolved (S)-esters with excellent ee. The acids were easily separated from the (S)-esters by a simple acid-base work-up. The overall yields of 1 and 2 were 16% and 17%, respectively. (C) 2009 Elsevier Ltd. All rights reserved.
