-toluenesulfonamido)phenyl]ethyl α- and β- d -glucopyranosides. Disaccharides having the structure α- d -Glc p -(1 → 2)-α- d -Glc p , α- d -Glc p -(1 → 3)-α- d -Glc p , β- d -Glc p -(1 → 2)-β- d -Glc p , and β- d -Glc p -(1 → 3)-α- d -Glc p were synthesized. The oligosaccharides were debenzylated with sodium in liquid ammonia to give disaccharides having a free primary aromatic amino group, which were converted
摘要2,3,4-三-O-苄基-6-O-(N-苯基氨基甲酰基)-1-O-甲苯磺酰基-d-吡喃葡萄糖和3,4,6-三-O-苄基-2-O-p使-硝基苯甲酰基-1-O-甲苯磺酰基-d-吡喃葡萄糖与部分封闭的2- [4-(对甲苯磺酰胺基)苯基]乙基α-和β-d-吡喃葡萄糖苷反应。结构为α-d -Glc p-(1→2)-α-d -Glc p的二糖,α-d -Glc p-(1→3)-α-d -Glc p,β-d -Glc p合成了-(1→2)-β-d-Glcp和β-d-Glcp-(1→3)-α-d-Glcp。将寡糖在液体氨中用钠脱苄基,得到具有游离伯芳族氨基的二糖,将其转化为异硫氰酸酯衍生物,然后与各种蛋白质偶联,得到相应的缀合物。
