  A New Method for Production of Chiral 2-Aryloxypropanoic Acids Using Effective Kinetic Resolution of Racemic 2-Aryloxycarboxylic Acids

  摘要：

  We report a novel method for the preparation of 2-aryloxypropanoic acids by kinetic resolution of racemic 2-aryloxypropanoic acids using enantioselective esterification. The usage of pivalic anhydride (Piv(2)O) as an activating agent, bis(alpha-naphthyl)methanol ((alpha-Np)(2)CHOH) as an achiral alcohol, and (+)-benzotetramisole ((+)-BTM) as a chiral acyl-transfer catalyst enables the effective separation of various racemic 2-aryloxypropanoic acids to afford optically active carboxylic acids and the corresponding esters with high enantioselectivities. Furthermore, theoretical calculations of the transition states required to form the chiral esters successfully proved the enantiomer recognition mechanism of the asymmetric esterification.

  enantiomerically pure (R)-(+)-DCPP and (S)-(-)-DCPP. The observed inhibition pattern was that of partial noncompetitive inhibition for (R)-(+)-DCPP and that of pure noncompetitive inhibition for (S)-(-)-DCPP. Enantioselective biocatalysis in aqueous' and nonaqueousZ media is becoming increasingly important as a possible alternative method for the resolution of enantiomers. In recent years, hydrolytic enzymes such

  Enzymatic hydrolysis of racemic 2-(mono-,di- and trichlorophenoxy)-propionic acids methyl esters by α-chymotrypsin, pig liver esterase and porcine pancreatic or lipases was found to be poorly to moderately enantioselective; in most cases, the R-ester was preferentially hydrolyzed.
