    Abstract: A strategy, or method, for the quantitative determination of enantiomeric purity that combines lin situ enantiomer diastereomerization', spectroscopy, and chemometric modeling. Spectral data for samples of known enantiomeric composition is subjected to a type of multivariate regression modeling known as partial least squares (“PLS-I”) regression. The PLS-I regression produces a mathematical model that can be used to predict the enantiomeric composition of a set of samples of unknown enantiomeric purity. In this strategy, the guest-host complexation utilizes improved chiral selector molecules, including chiral amines and chiral alcohols such as phenylethylamine and 1,2-propanediol, that form ion pairs or covalent bonds with the chiral analytes.
