## Abstract __meta__βSubstituted diphenylmethanols were enantioresolved by the method of chiral phthalic acid yielding enantiopure alcohols. Their absolute configurations were unambiguously determined by Xβray crystallography of chiral phthalate esters and/or by the ^1^H NMR anisotropy method using

## 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
