been synthesized. These optically pure compounds were sufficiently soluble in acetonitrile used as fluorescentlabelingreagents. Their excitation and emission maxima were observed at λ 500 and 550 nm in acetonitrile, respectively. Enantiomers in a racemic mixture could be analyzed by these reagents. Racemic Ibuprofen and alanine methyl ester were nicely separated by (R)-N-(2-hydroxy-1-phenylethyl)-
