threo/erythro‐Assignment of 1,3‐diol derivatives based on ¹³C NMR spectra

The NMR spectra of 1,3‐diols and γ‐alkoxy alcohols indicate that these compounds exist predominantly in a hydrogen bonded conformation. threo ‐ and erythro ‐diastereomers show distinct differences in their 13 C NMR spectra which may be used to assign the relative configuration to each individual member of a pair of diastereomers.
