    摘要:
    为了确定从细胞培养的紫锥菊提取物中分离出来的阿拉伯半乳聚糖的假定表位特征,我们合成了两种寡糖。整个合成路线基于(甲氧基二甲基)甲基(MIP)和(2-萘基)甲基醚(NAP)保护基团的成功结合。使用 DDQ 或 Pd-C/H2 可以选择性地去除该保护基团,然后就可以将受体进一步糖基化。我们使用了两种阿拉伯呋喃糖基供体化合物:2,3,5-三-O-乙酰基阿拉伯呋喃糖基三氯乙酰亚氨酸酯和过乙酰化的δ-(1→5)-连接二阿拉伯呋喃糖基三氯乙酰亚氨酸酯。四糖和五糖的脱保护采用了相同的程序。所有合成的化合物都通过 1H 和 13C NMR 光谱以及 MALDI-TOF 质谱法进行了表征。

  • Synthesis of an arabinogalactan-type octa- and two isomeric nonasaccharides. Suitable tuning of protecting groups

    An arabinogalactan-type double-branched octa- and two isomeric nonasaccharides were synthesized using the (2-naphthyl)methyl (NAP) and the acid sensitive but base stable (methoxydimethyl)methyl (MIP) protecting groups. The beta-(1-->6)-linked hexagalactan skeleton was synthesized having a benzyl and a (2-naphthyl)methyl (NAP) group at positions 2 of the second and the penultimate galactopyranosyl units, and this made possible sequential introduction Of U-L-arabinofuranosyl or alpha-L-arabinofuranosyl-(1-->5)-alpha-L-arabinofuranosyl side chains.

  • Selective removal of the (2-naphthyl)methyl protecting group in the presence of p-methoxybenzyl group by catalytic hydrogenation

    Selective cleavage of the (2-naphthyl)methyl (NAP) group in the presence of p-methoxybenzyl (PMB), benzyl and benzylidene groups was achieved by catalytic hydrogenation with a series of monosaccharides. At a disaccharide level, the PMB group was stable upon hydrogenolysis of the NAP, however, partial cleavage of benzyl ether functions was observed.

    In order to characterise the presumed epitopes of arabinogalactans, isolated from the extract of the cell-cultured Echinacea purpurea, two oligosaccharides were synthesized. The whole synthetic route was based on the successful combination of the (methoxydimethyl)methyl (MIP) and the (2-naphthyl)methyl ether (NAP) protecting groups. A β-(1→6)-linked trigalactoside was prepared, which contained a NAP ether at position 2′.This protecting group was selectively removed using either DDQ or Pd-C/H2 and the acceptor was ready for further glycosylation.We have used two arabinofuranosyl donor compounds: 2,3,5-tri-O-acetyl arabinofuranosyl trichloroacetimidate and a peracetylated α-(1→5)-linked diarabinofuranosyl trichloroacetimidate. For the deprotection of the tetra- and pentasaccharides a common procedure was used. All of the synthesized compounds were characterized by 1H and 13C NMR spectroscopy, as well as by MALDI-TOF mass-spectrometry.
