A new method has been developed for determining the absolute configurations of acyclic [5-or ~--methyl substituted secondary alcohols using their 2NMA esters. The 1H-NMR spectra of (R)-and (S)-2NMA esters of model compounds were measured, and A6 values (6R.este r --6S\_este r) for the corresponding

It is shown that the cheap and easily prepared mandelic acid esters (or their OAc analogues) are best suited than the expensive, although usually employed, OMe mandelic acid esters to assess both the enantiomeric excesses and absolute configurations of secondary alcohols.

Susanary -The kinetic resolution of racemic 2-phenylbutyryl chloride by hindered chiral secondary alcohols has been shown to be a viable approach to the determination of the absolute configuration of secondary alcohols through a study of ten chiral alcohols. For nearly three decades, Horeau's metho
