    具有潜在铜络合能力的半乳糖醛酸基大环化合物的便捷合成
    摘要:
    已经实现了构建含有酰胺基团和三唑环的基于半乳糖醛酸的大环的简便方法。关键步骤依赖于通过应用于炔烃-叠氮化物半乳糖醛酸酯的铜催化的分子内环加成反应有效形成 16 元环。1,3-偶极环加成反应的结果因反应条件而异;获得了预期的分子内 1,4-三唑以及不同比例的 C2 对称二聚体。对该大环对 CuII 阳离子的络合特性的初步研究表明,以 1:1 的金属/配体比形成穴状化合物。

However, the S-acetyl derivative of 17 could be obtained in good yield (62%) by LiAlH4 reduction of the crude mixture 17–19, followed by acetylation. The same sequence of reactions starting from 14 and the 1-thiolate of Galp afforded the per-O,S-acetyl derivative of Galp-β-S-(1→4)-3,4-dithio-α-d-Glcp-O-iPr (23), which was selectively

  • Synthesis of 5-deoxy-β-d-galactofuranosides as tools for the characterization of β-d-galactofuranosidases
    作者:Andrea Bordoni、Rosa M. de Lederkremer、Carla Marino
    DOI:10.1016/j.bmc.2010.05.038
    日期:2010.7
    Derivatives of 5-deoxy-beta-D-galactofuranose (5-deoxy-alpha-L-arabino-hexofuranose) have been synthesized starting from D-galacturonic acid. The synthesis of methyl 5-deoxy-alpha-L-arabino-hexofuranoside (14 alpha) was achieved by an efficient strategy previously optimized, involving a photoinduced electron transfer (PET) deoxygenation. Compound 14 alpha was converted into per-O-acetyl-5-deoxy-alpha,beta-L-arabino-hexofuranoside (16), an activated precursor for glycosylation reactions. The SnCl4-promoted glycosylation of 16 led to 4-nitrophenyl (19 alpha), and 4-methylthiophenyl 5-deoxy-alpha-L-arabino-hexofuranosides (20 alpha). The oxygenated analog 4-methylphenyl 1-thio-beta-D-galactofuranoside (23 beta) was also prepared. The 5-deoxy galactofuranosides were evaluated as inhibitors or substrates of the exo-beta-D-galactofuranosidase from Penicillium fellutanum, showing that the absence of HO-5 drastically diminishes the affinity for the protein.
