High-performance liquid chromatography (HPLC) was employed for resolution of enantiomers of chiral ring-substituted 1-phenyl-2- aminopropanes (amphetamines) and 1-phenylethylamine following derivatization with four chiral reagents: (R)-(+)-1-phenylethyl isocyanate ( PEIC ), (-)-alpha-methoxy-alpha-(trifluoromethyl)phenylacetyl chloride ( MTPA X Cl), 2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl isothiocyanate ( GITC )
