Diastereomeric alpha-boroxazolidone gamma-phenylethylamide (or gamma-phenylethanolamide) derivatives of 2-, 3- or 4-substituted glutamic acid analogues have been separated by silicagel chromatography, resulting, after deprotection, in a practical method for the resolution of most of these unnatural amino acids.
