Here we summarize the chemical syntheses of glycans containing over 20 monosaccharide units, with the recent syntheses of ultra-long glycans, including a 92mer arabinogalactan, a 100mer and a 151mer mannan, and a 128mer rhamnomannan, being highlighted. The assembly strategies, glycosylation methods, and protecting group manipulations, which are crucial to the successful synthesis, are discussed to give guidance for the future synthesis of various polysaccharides.
在这里，我们总结了含有 20 个以上单糖单元的聚糖的化学合成方法，重点介绍了最近超多糖的合成，包括一个 92 mer 的阿拉伯半乳聚糖、一个 100mer 和一个 151mer 的甘露聚糖，以及一个 128mer 的鼠李半乳糖甘露聚糖。讨论了组装策略、糖基化方法和保护基操作，这些对于成功合成至关重要，为未来各种多糖的合成提供了指导。
