Aromatic and heterocyclic 1-C-substituted derivatives of 1,5-anhydro-D-glucitol

Reaction of anomeric 1-O-acyl and 1-halide derivatives of 2,3,4,6-tetra-O-benzyl-D-glucose with anisole, ferrocene, thiophene, furan, and 1,3,5-trimethoxybenzene in the presence of a Lewis acid gives the corresponding C-beta-D-glucopyranosyl derivatives.
