    通过烯醇化,β-消除和分子内环加成使2'-羰基烷基-C-糖苷发生差向异构。
    摘要:
    用4%NaOMe处理葡萄糖,半乳糖,甘露糖,2-脱氧和2-叠氮基糖的2'-羰基-α-C-糖吡喃糖苷导致端基异构体异构化,使其各自的β-端基异构体具有良好或优异的收率。α-C-吡喃半乳糖苷(10)的2'-醛在氘代甲醇中的差向异构化作用使β-端基异构体在1'-位具有唯一的氘代取代作用,排除了外糖参与的可能性中间体。当使用2,3-二-O-苄基-α/β-1C-阿拉伯呋喃糖苷的2'-醛(36)和2'-酮(41)作为底物时,我们能够获得各自的赤道α-C-阿拉伯吡喃糖苷(37和42)。这些观察结果证实,差向异构体涉及无环的α,β-不饱和醛或酮,它是由2'-羰基-α-C-糖苷的烯醇化和随后的β-消除形成的。此后发生分子内杂-迈克尔环加成反应,导致形成热力学控制的稳定产物,该产物仅是赤道的C-糖吡喃糖苷,但2'-羰基-C-呋喃糖苷除外,其中获得了两种端基异构体的混合物。

    Facile Preparation of an Orthogonally Protected, pH-Sensitive, Bioconjugate Linker for Therapeutic Applications
    摘要:
    We describe the facile, three-step synthesis of an orthogonally protected, pH-sensitive linker (8), based on maleic acid, and report its application to the preparation of a pH-sensitive phospholipid (20) for potential use in drug and gene delivery. In addition, we highlight the benefits of our linker over the use of the commercially available cis-aconitic anhydride (4).

  • Design and Synthesis of a Novel Class of Sugar-Peptide Hybrids:  <i>C</i>-Linked Glyco β-Amino Acids through a Stereoselective “Acetate” Mannich Reaction as the Key Strategic Element

    on a new Mannich-type reaction between a chiral acetate enolate equivalent and alpha-amido sulfones derived from the corresponding sugar-C-glycoside aldehydes. While the sugar-C-glycoside aldehyde partner is prepared from well-established transformations on known sugar precursors, the lithium enolate derived from (1R)-endo-2-acetylisoborneol 3 is employed as the key element. This Mannich approach proceeds
    一种新型的糖-氨基酸杂交体,它由一个糖单元(葡萄糖、半乳糖或吡喃甘露糖)通过 C-糖苷键连接到 α-未取代的 β-氨基酸单元的 β-位,被表达。据推测,这些新化合物或由其衍生的寡聚肽可能具有 β-氨基酸寡聚体的结构特征以及 C-糖苷对水解的化学和酶抗性。该合成策略基于手性乙酸烯醇酯等价物与衍生自相应糖-C-糖苷醛的α-酰胺砜之间的新曼尼希型反应。虽然糖-C-糖苷醛伴侣是通过对已知糖前体的成熟转化制备的,以(1R)-endo-2-乙酰异冰片醇3衍生的烯醇锂为关键元素。这种曼尼希方法进行了基本上完美的非对映控制,导致新的 β-氨基羰基加合物以良好的收率。此外,通过用硝酸铈铵 (CAN) 进行氧化处理,可以顺利进行樟脑助剂的裂解。互补地,β-氨基羰基曼尼希加合物与α-或β-氨基酸残基的直接肽型偶联和随后的CAN促进辅助分离产生带有含糖脂肪族侧链的二肽片段,并且是一个过程可以迭代。还提供了基于实验

    1,2-Cyclopropaneacetylated sugar is an effective glycosyl donor, which reacted with various glycosyl acceptors including monosaccharides, amino acids and other alcohols in the presence of BF3•OEt2 or TMSOTf. The glycosylation is stereoselective in favor of β-anomeric products with BF3•OEt2 as catalyst, whereas TMSOTf-catalyzed glycosylation prefers the α-anomeric products. 2-C-Acetonyl-2-deoxy-d-galactosides

    A new immunostimulant, the 4′-epimer of α-C-GalCer, was synthesized from a C2-symmetric dienediol and α-C-allyl galactoside. The intramolecular aziridination and the following reductive ring opening provided the core of the aliphatic amino alcohol with excellent regio- and stereocontrol. The new immunostimulants 3d and 3e gave a better polarized Th1-type cytokine response in murine NKT cells than the

  • Exploiting the cross-metathesis reaction in the synthesis of pseudo-oligosaccharides
    作者:Paolo Ronchi、Stefano Vignando、Sara Guglieri、Laura Polito、Luigi Lay
    DOI:10.1039/b822989a
    日期:——
    An approach to the synthesis of pseudo-oligosaccharides based on the cross-metathesis reaction between distinct sugar-olefins, followed by intramolecular cyclization of the obtained heterodimer, is presented. In particular, the relative efficiency of two alternative approaches, the straightforward cross-metathesis reaction and the two-step procedure (self-metathesis followed by cross- metathesis), was explored and compared for diverse sugar-olefin substrates. Some representative examples of intramolecular cyclization using iodine as an electrophilic promoter, are also reported.
