An improved method for the preparation of 4,6-O-benzylidene-beta-D-glucopyranose (BG), and new or corrected data on its 1H and 13C NMR spectra, specific rotations, and tautomeric equilibria, and on those of its anomeric sodium salt (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 to beta-glucosides in reactions with strong electrophiles under strictly heterogeneous conditions.
