    A new glycosyl acceptor to be used in sialylation was designed as a 3-hydroxy derivative of 4-methoxyphenyl β-d-galactopyranoside with 2-O-acetyl group and O-4 and O-6 protected as benzylidene acetal. Two alternative syntheses of this compound were compared. Sialylation of 3-OH group of the glycosyl acceptor with O-chloroacetylated N-trifluoroacetylneuraminic acid phenyl thioglycoside (NIS, TfOH, MeCN
    设计了一种用于唾液酸化反应的新的糖基受体,它是4-甲氧基苯基β-d-吡喃半乳糖苷的3-羟基衍生物,带有2-O-乙酰基,O-4和O-6被保护为亚苄基乙缩醛。比较了该化合物的两种替代合成。在较宽的浓度范围(5-150 mmol L-)中研究了糖基受体的3-OH基与O-氯乙酰化的N-三氟乙酰神经氨酸苯基硫代糖苷(NIS,TfOH,MeCN,MS 3Å,-40°C)的唾液酸化1)。唾液酸化的结果通常遵循对MeCN中的唾液酸供体溶液的超分子分析的预测,该预测通过偏光法和静态光散射进行,并且揭示了溶液结构和糖基供体的超分子结构不同的两个浓度范围。
