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

13C NMR spectroscopy can be used for the quantitative analysis of mixtures of glycerides and the enantiomeric purity can be determined by using Eu(hfbc),-d reagent. This technique was applied to the study of the reaction mixture obtained from the transesterification of tributyrin catalysed by My-lip
## Abstract The enantiomeric purities of disubstituted β‐lactams were determined by ^1^H and ^13^C NMR spectroscopy using tris[3‐(trifluoromethylhydroxymethylene)‐d‐camphorato]europium(III), Eu(tfc)~3~, as a chiral shift reagent. Using a [Eu(tfc)~3~]/[lactam] ratio of 0.5, most of the resonances we
The stereochemistry of 1,Z-disubstituted fluoroethylenes, of general formula RCH,CH=CFR', has been ascertained from the different magnitudes of the upfield shift effect promoted by fluorine on the "C NMR absorptions of the underlined y-carbon of the fluorinated analogue in comparison with those of t
## Abstract The NMR spectra of a series of chiral propionamides have been determined in D(+)1‐phenylethylamine solution. The α‐methine protons of the propionic acid moiety in the propionamide enantiomers were found to be anisochronous in this solvent. The sense of non‐equivalence of these protons w
