摘要：

The title compound has been utilized for H-1 NMR spectral resolution of enantiomeric amino acids in aqueous solutions. For the alpha-protons of D,L-phenylglycine, an enantiomeric shift difference, DELTA-DELTA-delta = 0.4 ppm, was observed at an Eu(EDDS):substrate ratio of 0.3. Association constants between Eu(EDDS) and D,L-phenylglycine were found to be different for each isomer, K(L) = 3.7 and K(D) = 6.1. Spectral resolution of other amino acids including alanine, serine, threonine, and phenylalanine was also achieved.
