Abstract

The preparation of (S)-2-(4’-isobutylphenyl)propionic acid ((S)-Ibuprofen) (82% optical purity) and (S)-2-(6’-methoxy-2’-naphthyl)propioniacc id (Naproxen) (96% optical purity) has been accomplished by starting from optically pure (S)-2-chloropropionyl chloride. The investigation for finding the best experimental conditions and minimizing racemization phenomena is presented.
