    摘要:
    一系列2',3'-异丙叉和5'-三苯甲基保护的α-吲哚和α/β-苯并咪唑和咪唑核糖核苷用不同的酸脱保护。通过使用α-吲哚核糖核苷系列中的甲酸,实现了5'-2',3'-脱保护的选择性。在室温下用甲酸和乙醚的混合物处理α-吲哚核糖核苷得到2',3'-去保护的α-核糖核苷,而用相同的酸处理α-苯并咪唑核糖核苷得到5'-去保护的核糖核苷,而没有任何2',3'脱保护的产品。这些核糖核苷的结构已通过2D(NOESY,COSY和HMQC)NMR光谱进行了阐明。

  • STEREOSELECTIVE SYNTHESIS OF α-RIBONUCLEOSIDES FROM 1-HYDROXY SUGARS BY USING 2-FLUOROPYRIDINIUM TOSYLATE
    作者:Teruaki Mukaiyama、Yukihiko Hashimoto、Yujiro Hayashi、Shin-ichiro Shoda
    DOI:10.1246/cl.1984.557
    日期:1984.4.5
    A novel method for the preparation of α-ribonucleosides was developed by the use of 2-fluoro-1-methylpyridinium tosylate as a condensing reagent. Various α-ribonucleosides were synthesized from 1-hydroxy sugars and trimethylsilylated nitrogen compounds, such as nucleoside bases and azide, in good yields under mild conditions.

    trimethylsilyl- pyrazole. 1,-imidazole, 3,-5,6-dimethylbenzimidazole, 7, and 1,3,4-triazole, 8 with phosphorus pentafluoride was studied. The reaction proceeded via the initial formation of 1:1 Lewis acid-base adducts between phosphorus pentafluoride and the nitrogen atom bearing the Me3Si group. In the reaction of 1 with PF5 the unusual bis-tetrafluorophosphate complex. 2 was directly formed by cleavage

  • Regioselective Glycosylation: Synthesis of <i>α</i>-Indoline Nucleosides
    作者:Kenneth L. Brown、Tilak Chandra、Shawn Zou、Edward J. Valente
    DOI:10.1081/ncn-200067398
    日期:2005.7.1
    Novel indoline ribonucleosides with the alpha-N-glycoside configuration are synthesized with very high regioselectivily in 90-96% yield, using TMS protected indolines and 2,3-O-(1-methylethylidene)-5-O-(triphenylmethyl)-alpha/beta-D-ribofuranose. The structures of these ribonucleosides were elucidated with X-ray crystallography as well as 2D (NOESY COSY and HMQC) NMR spectroscopy.

    DOI:10.1016/j.tetlet.2005.09.180
    日期:2005.12
    Several protected benzimidazole and imidazole alpha-ribonucleosides were deprotected in excellent yield Lit ambient temperature using CBr4 initiated photolysis in methanol at ambient temperature. No selectivity was observed and both trityl and isopropylidene groups were deprotected Under the reaction conditions. (c) 2005 Elsevier Ltd. All rights reserved.
