    N-Trifluoroacetyl Sialyl Phosphite Donors for the Synthesis of α(2 → 9) Oligosialic Acids
    摘要:
    A new method for the synthesis of alpha(2 -> 9) oligosialic acids is developed using phosphite sialyl donors that are protected with a C-5 N-trifluoroacetyl (NHTFA) substituent. Compared with conventional donors, these donors gave a higher degree of alpha-anomeric selectivity during glycosidic bond formation and better yields during iterative sialylation in the synthesis of oligosialic acids.

  • Phosphite-based sialic acid donors in the synthesis of α(2→9) oligosialic acids

    The combination of a phosphite donor and an anomeric thiocresol-protected acceptor, both with a TFA protecting group at C-5 of the sialic acid, provides good α-selectivity and yield in sialylation. Although the convergent synthetic strategy of using a phosphite disialo-donor and a disialo-acceptor assembles tetra-sialic acid efficiently, overcoming the low α-selectivity of α-anomer and purifying it
    亚磷酸酯供体和异头醇甲保护的受体的组合,在唾液酸的C-5处均具有TFA保护基,在唾液酸化中提供了良好的α-选择性和产率。尽管使用亚磷酸酯二唾液酸供体和二唾液酸受体的会聚合成策略有效地组装了四唾液酸,但是仍然需要克服α-端基异构体的低α-选择性并对其进行纯化。此外,将单唾液酸和二唾液酸分别缀合在载体蛋白,匙孔血蓝蛋白上。建议使用酶解方法估算蛋白质偶联物上唾液酸的量。
