title: Diastereomeric Shape Recognition Using NMR Spectroscopy in a Chiral Liquid Crystalline Solvent.
abstract: Unambiguous assignment of the resonances of different diastereomers in a nonracemic mixture is possible with (1)H-decoupled (2)H NMR spectroscopy in a chiral liquid crystalline solvent. This is demonstrated with, for example, the alpha,alpha'-dideuterated diol shown in the picture. Even diastereomers with centers of chirality up to nine bonds apart can be discriminated.
