beta-0-Glycosides of N-acetylglucosamine with substituted 7-hydroxychromones and 7-hydroxycoumarins as the aglycones are synthesized The phenyl hydroxyls are O-glycosylated in a solid-liquid system with crown-ether catalysts. The structures of the chromone and coumarin N-acetylglucosaminides and their per-0-acetates are proved by PMR spectroscopy.
