  • Process for obtaining D(+)-naproxen
    Patent number: 4857462
    Abstract: A process for obtaining D-2-(6-methoxy-2-naphthyl)-propionic acid from a mixture of D- and L-2-(6-methoxy-2-naphthyl)-propionic acid lower alkyl esters is provided 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 lower alkyl ester and saponification of the latter, wherein the saponification is carried out enzymatically with esterase from hog liver or from Pleurotus ostreatus.
