  Chemoenzymatic synthesis and resolution of compounds containing a quaternary stereocenters adjacent to a carbonyl group

  摘要：

  Racemic compounds containing a quaternary stereocenter (having hydroxymethyl and alkyl group adjacent to keto functionality) based on chromanone, alpha-tetralone, and indalone scaffolds have been synthesized. An enzymatic irreversible transesterification approach has been applied to generate the pure enantiomers in a stereocontrolled fashion. The pure enantiomers of some alpha,alpha-dialkylated carbonyl compounds have been synthesized by this method. (C) 2008 Elsevier Ltd. All rights reserved.
