(RS)-2-methyl-4-octanol were resolved by using (S)-2-methoxy-2-(1-naphthyl)propanoic acid [(S)-MalphaNP acid]. The specific stereochemistry of each MalphaNP ester was elucidated by 2D NMR analyses, and shielding by the 1-naphthyl group was observed in both the 1H- and 13C-NMR spectra. Solvolysis of the individual (S)-MalphaNP esters gave four single-enantiomer alcohols. The normal-phase HPLC elution order
