  New chemo and chemo-enzymatic synthesis of β-benzyl-γ-butyrolactones

  摘要：

  beta-Benzyl-gamma-butyrolactones, important intermediates for the synthesis of butyrolactone lignans, have been synthesized by a new route involving preparation of alpha-beta-unsaturated formyl esters. The formyl esters can easily be converted into the desired butyrolactones either through chemical transformations or by enzymatic methods. (C) 2003 Published by Elsevier Science Ltd.
