    Stereocontrolled Synthesis of the d- and l-glycero-β-d-manno-Heptopyranosides and Their 6-Deoxy Analogues. Synthesis of Methyl α-l-Rhamno-pyranosyl-(1→3)-d-glycero-β-d-manno-heptopyranosyl- (1→3)-6-deoxy-glycero-β-d-manno-heptopyranosyl-(1→4)-α-l- rhamno-pyranoside, a Tetrasaccharide Subunit of the Lipopolysaccharide from Plesimonas shigelloides
    摘要:
    The synthesis of D-and L-glycero-alpha-manno-thioheptopyranosides, protected with 4,6-O-alkylidenetype acetals is described. In glycosylations carried out with preactivation with the 1-benzenesulfinylpiperidine/trifluoromethanesulfonic anhydride couple, both the D-and L-glycero series exhibit excellent, beta-selectivity with a range of glycosyl acceptors. In contrast, a 4,7-O-alkylidene acetal was found not to afford, beta-selectivity. With a 4,6-O-[1-cyano-2-(2-iodophenyl) ethylidene] acetal protected thioglycoside, excellent, beta-selectivity was obtained in glycosylation reactions, and subsequent treatment with tributyltin hydride and azoisobutyronitrile brought about clean fragmentation to the 6-deoxy-glycero-beta-D-manno-heptopyranosides. This chemistry was applied to the stereocontrolled synthesis of methyl alpha-L-rhamno-pyranosyl-(1 -> 3)-D-glycero-beta- D-manno-heptopyranosyl-(1 -> 3)-6-deoxy-glycero-beta-D-manno-heptopyranosyl-(1 -> 4)-alpha-L-rhamno-pyranoside, a component of the lipopolysaccharide from Plesimonas shigelloides.

    摘要:
    描述了交替 β-(1→4)-β-(1→3)-甘露六糖的甲基糖苷的两种立体控制合成,代表了来自粘红酵母、粘液红酵母和双弯曲钩端螺旋体的甘露聚糖。两种合成均采用 4,6-O-亚苄基和 4,6-Op-甲氧基亚苄基缩醛保护供体的组合,以实现 β-甘露糖苷键的立体控制形成。第一个合成是线性合成,并且始终进行高度立体控制,总产率为 1.9%。第二个合成,即嵌段合成,利用了两个三糖的偶联,得到了更短的序列和 4.4% 的总产率,尽管关键步骤的选择性很差。

    1, whereas a heptanoyl homolog (2w: C7) maintained activity nearly equal to that of 1. When the acyl groups at these three positions were substituted by an octanoyl group (2i: C8), the activity was completely lost. On the other hand, of the 10 homologs in which the octanoyl at C-2 was substituted by other acyloxy moieties (2j–2s), three (2m: C7, 2n: C9, 2o: C10) maintained potent activity. These results

    Acremonium strictum, by employing the stereoselective β-mannosylation of 4,6-O-benzylidene-protected mannosyl sulfoxide with d-mannitol as the key reaction is described. The α-anomer (epi-1) of 1 was also synthesized selectively. The calcium modulating activity was reduced upon inversion of the configuration at the anomeric center, indicating that the β-configuration of the mannose moiety is preferable for the

    The first synthesis of the inositol-containing marine glycolipid dioctadecanoyl discoside is reported. The key glycosylation reaction proceeds with β-selectivity at reduced temperature. The separable anomers could be readily progressed to afford discoside, its peracetate and the unnatural β-derivatives.

    日期:2010.10.15
    A new set of orthogonal protecting groups has been developed based on the use of a diethylisopropylsilyl (DEIPS), methylnaphthyl (Nap), allyl ether, and levulinoyl (Lev) ester. The protecting groups are ideally suited for the preparation of highly branched oligosaccharides and their usefulness has been demonstrated by the chemical synthesis of a β-d-Man-(1→4)-d-Man disaccharide, which is appropriately

  • Determination of the Influence of Side‐Chain Conformation on Glycosylation Selectivity using Conformationally Restricted Donors
    作者:Suresh Dharuman、David Crich
    DOI:10.1002/chem.201505019
    日期:2016.3.18
    The synthesis of a series of conformationally locked mannopyranosyl thioglycosides in which the C6−O6 bond adopts either the gauche,gauche, gauche,trans, or trans,gauche conformation is described, and their influence on glycosylation stereoselectivity investigated. Two 4,6‐O‐benzylidene‐protected mannosyl thioglycosides carrying axial or equatorial methyl groups at the 6‐position were also synthesized
    描述了一系列构象锁定的甘露糖代糖苷的合成,其中C6−O6键采用正向、正向、正向、反式或反式、正向构象,并研究了它们对糖基化立体选择性的影响。还合成了两种 4,6- O-亚苄基保护的甘露糖代糖苷,它们在 6 位上带有轴向或赤道甲基,并研究了它们糖基化反应的选择性,以区分空间效应和立体电子效应。双环供体中 C6 处存在轴向甲基会导致形成 β-甘露糖苷的偏好降低,而轴向甲基对选择性影响很小。该结果通过轴向甲基对瞬时中间体鎓离子的全空间稳定性进行了合理化,从而在糖基化反应中产生更高程度的 S N 1 样特征。与文献示例进行了比较,并根据基本立体电子效应之上的普遍空间效应讨论了例外情况。
