✦ Synopsis

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

Chlorophenoxypropionic acids Zb-f are well-known herbicides which are currently used as 1 racemates although only R-enantiomers are known to be biologically active . Acid 2b is also

The utilization of enzymes is a recent achievement in organic synthesis. There are many good reasons for the organic chemist to consider this approach. Enzymatic reactions are very fast and specific. The same transformations carried out by classical means in several days or weeks, can be achieved in
