  Synthesis of β-Glycosyl Formamides Through N-Glycosylation of Unprotected Carbohydrates

  摘要：

  Two new synthetic routes involving N-glycosylation of unprotected carbohydrates were developed for the preparation of beta-glycosyl formamides. Using this protocol, D-glucose, D-xylose, D-galactose and D-maltose were transformed to their corresponding beta-glycosyl formamides.
