Oxazolidine derivatives of p-amino alcohols such as ephedrine have been resolved by -C NMR spedroscopy using Eu(hfc), as a chiral shift reagent. The method is quantitative in the determination of enantiomeric excess, and is advantageous where 'H NMR is of limited use owing, for example, to signitica

Abstract
The enantiomeric excess (ee) can be determined by many methods; one among them is nuclear magnetic resonance in solid‐state (SS NMR). In this study we used the SS NMR ODESSA experiment for determination of the ee of valine. Copyright © 2006 John Wiley & Sons, Ltd.
