  • Benzeneselenenyl triflate as an activator of thioglycosides for glycosylation reactions
    作者:Yukishige Ito、Tomoya Ogawa、Masaaki Numata、Mamoru Sugimoto
    DOI:10.1016/0008-6215(90)84078-9
    日期:1990.7
    A new method for the activation of thioglycosides was developed by use of benzeneselenenyl triflate (PhSeOTf), which, upon reaction with either a primary or secondary sugar HO-group, afforded O-glycosides under extremely mild reaction conditions. The reaction was applicable to various l-thiohexosides 2-6 as well as to a 2-thioglycoside 20 derived from N-acetylneuraminic acid (NeuAc).
    通过使用苯烯基三氟甲磺酸酯(PhSeOTf),开发了一种活化代糖苷的新方法,该方法与伯或仲糖HO-基团反应后,在极其温和的反应条件下提供了O-糖苷。该反应适用于各种1-代己糖苷2-6以及衍生自N-乙酰神经氨酸(NeuAc)的2-代糖苷20。
  • Total synthesis of the modified ganglioside de -N-acetyl-GM3 and some analogs

    corresponding glycotriosyl donors which, upon coupling with (2S,3R,4E)-3-O-benzoyl-2-N-tetracosanoylsphingenine, afforded completely protected ganglioside analogs 39, 40, and 41, respectively. Deprotection of 40, 41, and 39 completed the synthesis of the modified ganglioside de-N-acetyl-GM3, a stereoisomer, and a regioisomer. The N-deprotected forms of 40 and 39, on successive treatment with methyl isocyanate

  • Studies Directed toward the Synthesis of Polysialogangliosides: The Regio- and Stereocontrolled Synthesis of Rationally Designed Fragments of the Tetrasialoganglioside GQ<sub>1b</sub><sup>+</sup>.
    作者:Yukishige Ito、Shigeki Nunomura、Shohei Shibayama、Tomoya Ogawa
    DOI:10.1021/jo00032a601
    日期:1992.3
    The synthesis of suitably protected fragments of the tetrasialoganglioside GQ1b (I), i.e., 1 (alpha-NeuAc2 -->-8-alpha-NeuAc2 --> 3-beta-Gal1 --> 4Glc), 2 (alpha-NeuAc2 --> 8-alpha-NeuAc2 --> 3Gal), 3 (GalNAc), 4 (alpha-NeuAc2 --> 8NeuAc), 5 (beta-Gal1 -->- 3GalNAc), and 42 [beta-Gal1 --> 3-beta-GalNAc1 --> 4(alpha-NeuAc2 --> 3)beta-Gal --> 4Glc], is described. All are rationally designed so that the protecting groups can be regioselectively introduced and removed, as needed, before or after the stereoselective coupling of an appropriate pair of fragments. The syntheses of 1, 2, and 4 all feature stereoselective glycosylations by glycosyl donors that bear a C-3 thiophenoxy stereocontrolling auxiliary. Compound 3 was prepared from the D-glucosamine derivative 17 by way of a novel intramolecular nucleophilic displacement with inversion of configuration. Furthermore, model glycosylations of 4-hydroxygalactose derivatives, in which the thioglycoside 3 and the fluoride 40 served as glycosyl donors, were performed. The reaction of 3 with the glycosyl acceptor 30 gave the disaccharide 31 (GalNAc-beta-1 --> 4Gal), whereas that of 40 with 41 afforded the pentasaccharide 42.
