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.

Crystal structures of sugar formamides and isocyanides of mono‐, di‐ and trisaccharides were analyzed, revealing useful structural information. Trends were obtained which were utilized in the design and synthesis of glycosyl adducts bearing macrocycle, lactone and indole derivatives
