PROCESS FOR OBTAINING D-2-(6-METHOXY-2-NAPHTHYL)-PROPIONIC ACID

摘要

1. Process for the obtaining of D-2-(6-methoxy-2-naphthyl)-propionic acid from mixtures of D- and L-2-(6-methoxy-2-naphthyl)-propionic acid esters of alkyl alcohols with 1 to 4 carbon atoms by asymmetric hydrolysis of the L-ester with a microbial enzyme, separation of the 2-(6-methoxy-2-naphthyl)-propionic acid from the D-2-(6-methoxy-2-naphthyl)-propionic acid ester and saponification of the latter, characterised in that one carries out the saponification enzymatically with esterase from hog liver or Pleurotus ostreatus.
