DL-N-ACETYL-2-(4-ACETOXIFENYL)GLYCIN ELLER EN OPTISK ISOMER ELLER DEHYDROABIETYLAMINSALTET DERAV FOR ANVENDNING SOM MELLANPRODUKT VID FRAMSTELLNING AV 2-(4-HYDROXIFENYL)GLYCIN I EN OPTISKT AKTIV FORM

摘要

DL-2-(4-Hydroxyphenyl)-glycine is resolved into optically-active forms by forming an N,O-diacyl derivative of 2-(4-hydroxyphenyl)-glycine, preferably an acetyl derivative, forming diastereomeric salts thereof with dehydroabietylamine and separating such salts by crystallisation, followed by decomposition and hydrolysis.
