    Efficient synthesis of core 2 class glycosyl amino acids by one-pot glycosylation approach
    摘要:
    We describe the one-pot synthesis of core 2 class branched oligosaccharides initiated by chemo-selective glycosylation of silyl anther. Glycosylation of 6-O-silyl-4-benzyl-2-azido-thiogalactoside with glycosyl fluoride provided selectively 6-glycosylated thioglycoside without both O-glycosylation at the 3 position and S-glycosylation. Subsequent coupling of galactosyl fluoride and amino acids afforded the protected branched oligosaccharides in good yields. (C) 2003 Elsevier Ltd. All rights reserved.

    摘要:
    对两种具有 RS 构型的轴向糖基硫醚(苯基 2-叠氮-2-脱氧-1-硫代-α-d-吡喃半乳糖苷 S-氧化物的衍生物)进行的 X 射线晶体学研究表明,它们在固态中呈现反构象,这与之前的观察和假设截然不同。在 B3lYP6-311G+(d,p)/6-31G(d)水平上进行的密度泛函理论(DFT)计算证实,2-叠氮-2-脱氧-α-d-吡喃糖苷的苯基和甲基 RS 糖基硫醚的反构象比气相中的外异构构象更稳定。一维 NOE 测量结果表明,极性较强的外异构体构象在溶液中只占很小的比例。反构象发生了扭曲,使糖基取代基更接近于被 H1 遮挡。如果硫孤对子是 p 型孤对子,则这种扭曲会使 S n → σ* 重叠。这种重叠的证据来自较短的 C1-S 键距离,与 X 射线晶体结构中的可比键距离以及 SS 糖苷的 DFT 计算结果一样短,SS 糖苷在固态和溶液中都采用了预期的外异构构象,并具有正常的 n → σ* 重叠。对于不含 2-叠氮基团的 2-脱氧衍生物,相同水平的气相 DFT 计算表明,反异构构象和外异构构象具有相当的稳定性。对这两个系列的结果进行比较后发现,位于 C2 赤道方向的电负性取代基会使 S-O 平行排列的构象不稳定,而内环 C-O 偶极子与 S-O 偶极子反平行则有利于这种构象,不稳定程度约为 2.5 kcal mol-1 (1 cal = 4.184 J)。X 射线衍射显示,一种赤道糖基亚砜,即 (SS) 苯基 3,4,6-三-O-乙酰基-2-脱氧-2-酞酰亚胺基-1-硫代-β-d-吡喃葡萄糖苷 S-亚砜,在固态下也采用了反构象。它在溶液中也采用这种构象,这与对其他赤道糖基硫醚的研究不同。

    An object of the present invention is to provide a method for efficiently chemically synthesizing biomolecules including a nucleotide (nucleic acid), a peptide (protein), or a sugar chain, as representative examples. The present invention provides a method of solid-phase synthesis of sugar chain(s) for synthesizing multiple types of sugar chains in at least one sugar chain synthesis reaction system comprising multiple types of monosaccharide units, which is characterized in that it comprises changing the temperature in the sugar chain synthesis reaction system depending on the temperature rising rate that has been determined based on a decrease in side reaction(s) in the reaction system as an indicator.
