A series of D-allal and D-glucal derivatives were examined by 13C N.M.R. spectroscopy. Assignments of 13C resonances were established by standard chemical shift considerations, lanthanide shift reagent and proton chemical shift correlations. Configuration-induced chemical shift variations are reported between the glucal and allal systems.
