Abstract

Reaction of C-β-d-glycopyranosyl-1,4-dimethoxybenzenes with acetyl nitrate afforded 2-(β-d-glycopyranosyl)-1,4-dimethoxy-5-nitrobenzenes in high yields. These were converted smoothly (reduction to amines, N-acylation, oxidation, and reduction) into the corresponding C-glycosyl-hydro(benzo)quinone derivatives, with different amide-based substituents at C-5. Reduction of the nitro compounds to amines proceeded smoothly by catalytic hydrogen transfer with HCO2NH4.
