An improved method for the preparation of 4,6-O-benzylidene-D-glucopyranose (BG), and new or correlated data on its 1H and 13C NMR spectra, specific rotations, and tautomeric equilibria, and on those of its anomeric sodiumsalt (BGNa), are reported. Evidence is presented in favour of the hypothesis that crystalline BGNa exists entirely in its beta-anomeric form and that it can be useful in the access
