  摘要：

  The synthesis of beta-(2-methyl-3-phenylchromonyl-7)- and beta-[2-methyl-3-(3,4-trimethylenedioxy) phenylchromonyl-7]glycosides of the methyl ester of N-acetylmuramoyl-L-alanyl-D-isoglutamine, new derivatives of a muramoyldipeptide with chromone aglycones, is described. The starting arylglycosides of N-acetylglucosamine are prepared by glycosylation of 7-hydroxychromone derivatives with the peracetate of alpha -glucosamine chloride catalyzed by a crown ether. The synthesized beta -aryl-4,6-O-isopropylidene-N-acetylmuramic acids are condensed with the dipeptide and deprotected to give the desired glycopeptides.

  摘要：

  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.
