  • Chemoselective Removal of Protecting Groups from <i>O</i>-Glycosyl Amino Acid and Peptide (Methoxyethoxy)ethyl Esters Using Lipases and Papain
    作者:Jörg Eberling、Peter Braun、Danuta Kowalczyk、Michael Schultz、Horst Kunz
    DOI:10.1021/jo951899j
    日期:1996.1.1
    selective C-terminal deprotection of O-glycopeptide (methoxyethoxy)ethyl esters is achieved under mild conditions (pH 6.6, 37 degrees C) by enzymatic hydrolysis using papain or lipase M from Mucor javanicus to give building blocks useful for chain-extending glycopeptide synthesis. On the other hand, the selective removal of acetyl protecting groups from the saccharide portion of glycopeptides is accomplished
    O-糖肽(甲氧基乙氧基)乙酯的选择性C末端脱保护是在温和条件下(pH 6.6,37摄氏度),通过木瓜蛋白酶或木脂酶M的脂肪酶M酶促解实现的,从而提供了可用于扩链糖肽合成的结构单元。另一方面,从糖肽的糖部分选择性除去乙酰基保护基团是通过用脂肪酶WG从小麦胚芽中进行选择性酶解,为酶促糖基转移反应提供模型底物来实现的,以延长这些缀合物的碳水化合物侧链。 。
  • Gram scale synthesis of A (type 2) and B (type 2) blood group tetrasaccharides through 1,6-anhydro-N-acetyl-β-D-glucosamine

    Fuc-Gal-anhydroGlcNAc with single free 3'-OH group. Its standard α-galactosylation gave protected B (type 2) tetrasaccharide. For synthesis of correspondent A tetrasaccharide seven different 2-azido-2-deoxygalactosyl (GalN3) donors were tested: 6-O-acetyl-3,4-O-isopropylidene-GalN3 thioglycoside was shown to provide the best yield (89%) and stereoselectivity (α/β = 24:1). Further 1,6-anhydro cycle opening
    从3-O-苯甲酰基-1,6-脱-N-乙酰基葡糖胺开始,提出了以3-基丙基糖苷形式的A(2型)和B(2型)四糖的革兰氏合成。其半乳糖基化,然后再保护,得到具有单个游离2'-OH基团的乳糖胺衍生物,总产率为75%。标准岩藻糖基化和下一轮再保护的总产率为88%,得到具有单个游离3'-OH基团的三糖Fuc-Gal-anhydroGlcNAc。其标准的α-半乳糖基化得到保护的B(2型)四糖。为了合成对应的A四糖,测试了七个不同的2-叠氮基-2-脱氧半乳糖基(GalN3)供体:6-O-乙酰基-3,4-O-异亚丙基-GalN3代糖苷提供了最佳收率(89%),立体选择性(α/β= 24:1)。进一步打开1,6-脱循环,
  • Syntheses of Anomerically Phosphodiester-Linked Oligomers of the Repeating Units of the <i>Haemophilus </i><i>i</i><i>nfluenzae</i> Types c and f Capsular Polysaccharides
    作者:Jonas Hansson、Per J. Garegg、Stefan Oscarson
    DOI:10.1021/jo001302m
    日期:2001.9.1
    trimers of the repeating units of the capsular polysaccharide of Haemophilus influenzae type c, -4)-3-O-Ac-beta-D-GlcpNAc-(1-->3)-alpha-D-Galp-(1-OPO(3-)-, and type f, -3)-beta-D-GalpNAc-(1-->4)-3-O-Ac-alpha-D-GalpNAc-(1-OPO(3-)-, have been synthesized for use in immunological studies. H-Phosphonate chemistry was used for the formation of the interglycosidic phosphate diester linkages. Two types of building
    通过从α/β混合物中结晶前体半缩醛的纯α-异头物结晶,在c型中形成α-连接的单酯H-膦酸酯的立体特异性是可能的,而在f型中,半缩醛的分离是直接分离的α-异头物。随后使用三咪唑基膦进行膦酰化而不进行异构化。使用新戊酰氯作为偶联剂,进行异头磷酸二酯键的形成,然后对形成的二酯H-膦酸酯进行I(2)/ H(2)O氧化。原始实验完全没有提供二酯产物,但是优化氧化条件(降低温度和在加入I(2)之前用吡啶稀释)可以得到良好的二聚体收率(71%和81%),随后,除去二聚体中的临时甲硅烷基保护基团后,三聚体的收率合理(36%和37%),并伴随着二聚体磷酸酯键的解。通过催化氢解的一步脱保护有效地提供了目标二聚体(30和36)和三聚体结构(32和39)。合成方案允许进一步延伸以得到更高的低聚物。

  • Synthesis of Zwitterionic 1,1′-Glycosylphosphodiester: A Partial Structure of Galactosamine-Modified <i>Francisella</i> Lipid A
    作者:David Baum、Paul Kosma、Alla Zamyatina
    DOI:10.1021/ol501639c
    日期:2014.7.18
    Synthesis of a "double glycosidic" phosphodiester comprising anomeric centers of two 2-amino-2-deoxy-sugars is reported. The carbohydrate epitope of Francisella lipid A modified with alpha-D-galactosamine at the anomerically linked phosphate has been stereoselectively prepared and coupled to maleimide-activated bovine serum albumin via an amide-linked thiol-terminated spacer group. H-Phosphonate and phosphoramidite approaches have been explored for the coupling of 4,6-DTBS-2-azido-protected GalN lactol and peracetylated spacer-equipped reducing beta GlcN(1 -> 6)GlcN disaccharide via phosphodiester linkage. Deprotection conditions preserving the integrity of the labile glycosidic zwitterionic phosphodiester were elaborated.
