We report convenient syntheses of anomeric quaternary ammonium β-glucosides in both protected and deprotected forms, together with X-ray structural investigations of two of the products. Both the quaternisation of a protected anomeric N,N-(dimethylamino)glucose, derived in two high-yielding steps from the anomeric azide, and the direct reaction of glucose or 6-O-trityl glucose with a secondary amine
