β¦ Synopsis
Previous papers in this series (l-5) have shown that the enanticmers of secondary and tertiary alcohols may be caused to have nonequivalent nmr spectra through the use of appropriate optically active amines as solvents. The converse of this phenomenon also obtains; amine

## Abstract The enantiopure of (__R__)β(β) MΞ±NPA was allowed to react with racemic 18β(__tert__βbutyldimethylsilyloxy)β5βoctadecayneβ7βol which was derived from dodecaneβ1,12βdiol, yielding diastereomeric esters mixture. These racemic esters were easily separated by HPLC on silicaβgel. The absolute
