  • Simple and Rapid Procedures for the Synthesis of 5-Acylated 4β-Acylamido- and 4β-Acetoxyneuraminic Acid Glycals
    作者:Irene S. Agnolin、Paola Rota、Pietro Allevi、Antonio Gregorio、Mario Anastasia
    DOI:10.1002/ejoc.201201001
    日期:2012.10.8
    Two simple and rapid procedures affording 4β-acylamido- and 4β-acetoxyneuraminic acid glycals acylated or perfluoroacylated at the 5-amino group are reported. The first protocol avoids the formation of oxazolines to synthesize the 4β-acetamido glycals through the Ritter reaction. The second passes through the oxazoline derivative to prepare 4β-acetoxyneuraminic acid glycals. Both protocols start from
    报告了两种简单快速的程序,可在 5-基上酰化或全氟酰化 4β-酰基-和 4β-乙酰氧基神经酸糖基。第一个协议避免了恶唑啉的形成,以通过 Ritter 反应合成 4β-乙酰基糖。第二个通过恶唑啉衍生物制备 4β-乙酰氧基神经酸聚糖。两种方案都从全乙酰化甲基神经酸开始,在基处用正常、乙二醇全氟酰基或相应的全乙酰化糖基甲基酯(DANA 或 FANA 系列)酰化。
  • Reaction of N-acetylneuraminic acid derivatives with perfluorinated anhydrides: a short access to N-perfluoracylated glycals with antiviral properties

    DOI:10.1039/c004938g
    日期:——
    An efficient short protocol for the preparation of N-perfluoroacylated glycals of neuraminic acid, by simple short treatment of differently protected N-acetylneuraminic acid with perfluorinated anhydrides in acetonitrile at 135 °C, is reported, together with a rationalitazion of the reaction that allows the alternative formation of N-perfluoroacylated 1,7-lactones to be previewed under the same reaction conditions.
    本报告介绍了一种高效制备神经酸 N-全氟乙酰缩水甘油酯的简易方案,即在 135 ℃ 下,在乙腈中用全氟酸酐对不同保护的 N-乙酰基神经酸进行简单的短时间处理,同时还介绍了该反应的合理性,从而可以在相同的反应条件下预览 N-全氟乙酰化 1,7 内酯的另一种生成方法。
  • Synthesis and Biological Evaluation of Several Dephosphonated Analogues of CMP-Neu5Ac as Inhibitors of GM3-Synthase

    hypoxic stress, suggesting that a pharmacological inhibition of the GM3 synthesis could be instrumental for the development of new treatments for ischemic diseases. Herein, the synthesis of several dephosphonated CMP‐Neu5Ac congeners and their anti‐GM3‐synthase activity is reported. Biological activity testes revealed that some inhibitors almost completely blocked the GM3‐synthase activity in vitro and reduced
    先前的研究表明,降低成肌细胞中GM3的含量会增强细胞对缺氧应激的抵抗力,这表明对GM3合成的药理抑制作用可能有助于开发缺血性疾病的新疗法。在这里,有几个dephosphonated CMP-Neu5Ac的同类物的合成及其抗-报道GM3合酶活性。生物活性睾丸显示,一些抑制剂在体外几乎完全阻断了GM3合酶的活性,并降低了活的胚胎肾脏293A细胞中GM3的含量,最终激活了表皮生长因子受体(EGFR)信号级联。
  • High yielding N-transacylation of secondary amides in acids labile molecules by the action of perfluorinated anhydrides in the presence of a mild base
    作者:Paola Rota、Pietro Allevi、Maria L. Costa、Mario Anastasia
    DOI:10.1016/j.tetasy.2010.10.019
    日期:2010.11
    The simple addition of mild bases (Et3N or DIPEA) allows a high yielding N-transacylation of secondary amides, performed by perfluorinated anhydrides, in molecules that are very sensitive to acids.
