resolution methods have been applied for the asymmetricsynthesis of pharmaceutical arylpropionic acids and aryloxy acids by using amides of (S)-lactic acid as chiralauxiliaries. For arylpropionic acids the esterification mediated by dicyclohexylcarbodiimide (DCC) and 4-(dimethylamino)pyridine (DMAP) proceeds with good asymmetric induction, while for aryloxyacetic acids the key-step is a diastereoselective
