Limitations in determining enantiomeric excess of alcohols by 31P-NMR of the phosphonate derivatives

The use of diastereomeric alcohol dialkylphosphonate derivatives to determine the enantiomeric excesses via 31P-NMR signal ratios of anisochronous meso and threo isomers was successfully applied to secondary alcohols (Feringa?s method). Expansion of the methodology to primary alcohols possessing the...
