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

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
