[Non-steroidal anti-inflammatory agents. V. Optically active 4-biphenylyloxybutyric and 4-biphenylylglycolic acids]

The synthesis and the resolution of the enantiomers of (+/-)2-(4-biphenylyl)-4-oxybutyric and (+/-)4-(4-biphenylyl)-2-oxybutyric acids and the resolution of the enantiomers of (+/-)2-(4-biphenylyl)-2-oxybutyric and (+/-)4-biphenylylglycolic acids are described. The potassium salts of each enantiomer were submitted to preliminary assays of antiphlogistic activity.
