configuration. This study investigated the use of 2-azido-2-deoxythioglycosides for 1,2-trans-β-glycosidic bond formation under low-concentration glycosylation conditions. Further application of the 2-azido-2-deoxythioglycosyl substrates for one-pot oligosaccharide synthesis was demonstrated in the synthesis of protected β-(16)-N-acetylglucosamine trimer, core-6–serine conjugate, and F1–α serine conjugate.
大多数天然 2-乙酰氨基-2-脱氧糖苷以 1,2-反式-β-糖苷构型存在。本研究调查了 2-叠氮基-2-脱氧硫糖苷在低浓度糖基化条件下用于 1,2-反式-β-糖苷键形成的用途。2-叠氮基-2-脱氧硫糖基底物在一锅寡糖合成中的进一步应用在受保护的β-(16)-N-乙酰氨基葡萄糖三聚体、核心6-丝氨酸偶联物和F1-α丝氨酸偶联物的合成中得到了证明。
