Abstract

An analytical HPLC method using CHIREX (S)-LEU/(S)-alpha-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 amidolactones, derived from l-glutamic acid, were undertaken.Copyright 2005 Wiley-Liss, Inc.
