N-ethoxycarbonylation was combined with (S)-1-phenylethylamidation for enantioseparation of amino acids by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) on achiral capillary columns. The method provided complete enantioseparations of 12 amino acids as diastereomeric N-ethoxycarbonyl/(S)-1-phenylethylamides with exceptional resolutions for proline
