Determination of absolute configuration and optical purity of partially active secondary carbinols by NMR spectroscopy has been the subject of many investigations. l-3 However, configurational assignment of secondary carbinols in an epimeric mixture has so far been limited to the case where the defi

The LIS values produced by Eu(fodJ3 for the CF3-19F NMR signals of the MlTA e s t e r s of different stereoisomeric secondary alcohols have been measured. The applicability o f these values for assigning the absolute configuration of the alcohols has been studied. The advantages of t h i s method ov
Determination of absolute configuration and enantiomeric purity of d-amino acids using chemical shift nonequivalence has been well investigated, 132 while little was reported3 on the successful application correlating the absolute configuration of amino acids with their relative magnitude of lanthan
