preparing unenriched and [1-13C]-enriched 5-deoxy- and 5-O-methyl-pentoses in the D or L configuration. The 1H-n.m.r. spectra of these compounds have been interpreted, and the 13C-n.m.r. spectra assigned with the aid of 2-D 13C-1H chemical-shift correlation spectroscopy. Tautomeric forms (furanoses, hydrate, and aldehyde) in solution in 2H2O have been quantified with the aid of [1-13C]-enriched derivatives
