A new biocatalyst for the preparation of enantiomerically pure 2-arylpropanoic acids
摘要:
A new biocatalyst. a strain of Pseudomonas fluorescens MTCCB0015. is described. which produces ibuprofen. ketoprofen and flurbiprofen as enantiomerically pure (S)-2-arylpropanoic acids from their corresponding racemic esters. 2-Arylpropanoic acids are an important class of non-steroidal anti-inflammatory, compound,. whose anti-inflammatory activity is mainly due to the (S)-enantiomer.

A highly chemoselective and reactive μ‐oxo‐dinuclear iron(III) salen catalyst for transesterification was developed. The developed ironcomplexcatalyzed acylation of aliphatic amino alcohols with nearly perfect O‐selectivity, even when using activated esters, for which chemoselectivity is more difficult to control. In addition, O‐selective transesterification of aromatic amino alcohols was achieved
