characterization of new (S)-(+)- and racemic phenylsuccinamic acids, obtained from the reaction of (S)-(+)-phenylsuccinic anhydride (1) with five different primary amines (2a-e) is described.Ring opening of anhydride 1 led to the formation of two isomeric phenylsuccinamic acid products with the phenyl substituent β to the amide function being the preferred product. Complete racemization occurred with all of the
