## Abstract An analytical HPLC method using CHIREX (__S__)‐LEU/(__S__)‐α‐NEA column was developed for the determination of the enantiomeric excesses of __N__‐protected (__S__)‐3‐hydroxyglutarimides. Using this method, detailed studies on the base‐promoted ring‐expansion reaction of the amidolactone
