Primary 1-deuterlo alcohols, RCHDOH, which are chiral have great value in the study of mechanisms of chemical merically pure alcohols of this type have been obtained various chemical asymmetric reactions have been used to by virtue of deuterium substitution, and biochemical reactions. 2.3 Enantioinvariably by enzymic processes, but

## Abstract The enantiomeric purities of disubstituted Ξ²βlactams were determined by ^1^H and ^13^C NMR spectroscopy using tris[3β(trifluoromethylhydroxymethylene)βdβcamphorato]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 13C NMR behaviour of ten acyclic terpene alcohols was examined in the presence of a chiral lanthanide shift reagent (CLSR). For each alcohol, we measured the lanthanide-induced shift (LIS) on the signals of the carbons and the splitting of some signals, which allowed the enantiomeric differentia
