摘要：

The utility of the Eu(III) derivative of (S, S)-ethylendiamine-N, N'- disuccinic acid, Eu(EDDS), has been investigated for its use as a chiral aqueous shift reagent. Upfield shifts were observed for the a-protons of (R)- and (S)-phenylglycine, and an enantiomeric shift difference as large as 0.4 ppm was observed at an Eu(EDDS)/substrate ratio of 0.3. It was deduced from these studies that Eu(EDDS) functions as a superior chiral shift reagent above pH 8. © 1990, Taylor & Francis Group, LLC. All rights reserved.
