    摘要:
    描述了TACA二聚体Lex的四糖和五糖片段的收敛合成。合成策略依赖于制备两个葡糖胺残基的O-3均不含的受保护的GlcNTCA-(1,3)-Gal-(1,4)-GlcNAc三糖二醇。制备该二醇的关键步骤包括在40°C下用BF3·Et2O活化三氯乙酰亚氨酸酯在N-乙酰氨基葡糖的O-4处进行糖基化,用硫脲除去非还原性O-3'氯乙酸末和糖基化。 N-三氯乙酰胺基氨基葡萄糖三氯乙酰亚胺酸酯供体。转化为二醇受体后,三糖在NIS / TMSOTf激活下的非还原端被选择性地岩藻糖基化,或在CuBr2 / Bu4NBr激活下被二岩藻糖基化。然后在溶解的金属条件下将被保护的四糖和五糖有效地脱保护,并且在反应后处理中非还原性末端葡糖胺残基被N-乙酰化。脱保护的化合物将用作可溶性竞争剂,以表征被抗聚合Lex抗体识别的表位。

    The convergent synthesis of tetra- and penta-saccharide fragments of the TACA dimeric Lex is described. The synthetic strategy relied on the preparation of a protected GlcNTCA-(1,3)-Gal-(1,4)-GlcNAc trisaccharide diol free at O-3 of both glucosamine residues. Key steps in the preparation of this diol involved glycosylation at O-4 of N-acetylglucosamine using activation of a trichloroacetimidate with
