  • Convenient Synthesis of Nucleoside and Isonucleoside Analogues
    作者:Luis Álvarez de Cienfuegos、Antonio J. Mota、Rafael Robles

    日期:2005.5.1
    methodology to stereoselectively achieve tricyclic isonucleosides (nucleobase = thymine, uracil, and 5-fluoruracil) and 3'-C-branched nucleosides (nucleobase = theophylline) was performed by means of a DBU-mediated addition process using a readily available 2-bromo sugar. The mechanism for these transformations implies the loss of both substituents at C-2 and C-3 on the sugar moiety, and although it

  • Furanosyl Oxocarbenium Ion Conformational Energy Landscape Maps as a Tool to Study the Glycosylation Stereoselectivity of 2‐Azidofuranoses, 2‐Fluorofuranoses and Methyl Furanosyl Uronates

    reactive intermediates is dictated by the conformation of these species. The nature and configuration of functional groups on the carbohydrate ring affect the stability of glycosyl oxocarbenium ions and control the overall shape of the cations. We herein map the stereoelectronic substituent effects of the C2‐azide, C2‐fluoride and C4‐carboxylic acid ester on the stability and reactivity of the complete
    糖基氧碳鎓离子的3D形状决定了它们的稳定性和反应性,在这些反应性中间体上发生的S N 1反应的立体化学过程取决于这些物质的构象。碳水化合物环上官能团的性质和构型影响糖基氧碳鎓离子的稳定性,并控制阳离子的整体形状。我们在本文中通过组合计算和实验方法,绘制了C2-叠氮化物,C2-氟化物和C4-羧酸酯的立体电子取代基对整套非对映异构呋喃糖酶的稳定性和反应性的影响。出乎意料的是,所有研究的呋喃糖基供体都以高度立体选择性的方式反应,从而生成1,2-顺式产品,木糖系列反应除外。核糖,阿拉伯糖和lyxo构成的呋喃糖苷的1,2-顺式选择性可以追溯到中间氧碳鎓离子的最低能量3 E或E 3构象异构体。对木糖基供体的选择性缺乏与采用其他构象的氧碳鎓离子的出现有关。
  • Synthesis of 2′-deoxy-2′-phenylselenenyl-furanosyl nucleosides from glycals using electrophilic selenium reagents. Conversion into 2′-deoxynucleosides
    作者:Yolanda Díaz、Anas El-Laghdach、Sergio Castillón

    nucleosides have been synthesized stereoselectively from glycals using selenium reagents, and converted into 2′-deoxynucleosides by treatment with tributyltin hydride. Some of the factors which affect the stereoselectivity of the reaction are the stereochemistry at position 3, the nature of the protecting groups, the phenylselenenyl reagent and the solvent.

  • Synthesis of erythro and threo furanoid glycals from 1- and 2-phenylselenenyl–carbohydrate derivatives
    作者:Fernando Bravo、Mohamed Kassou、Yolanda Dı́az、Sergio Castillón

    日期:2001.11
    Differently protected erythro and threo furanoid glycals were synthesized by selenoxide elimination when phenyl 1-selenoglycosides were treated in oxidizing conditions ((BuOOH)-Bu-i, Ti((OPr)-Pr-i)(4), (Et2PrN)-Pr-i). The phenyl 1-selenoglycosides were obtained from methyl 2-deoxy-D-erythro-pentofuranoside by protection of the primary hydroxyl or both hydroxyls and further reaction with PhSeH in the presence of BF3. Et2O. Erythro and threo furanoid glycals were also prepared by treating 2-deoxy-2-phenylselenenyl-1,4-anhydrocyclitols under similar conditions. The 2-deoxy-2-phenylselenenyl-1,4-anhydrocyclitols were obtained from 4-pentene-1,2,3-triols by a 5-endo selenium electrophilic induced cyclization. (C) 2001 Published by Elsevier Science Ltd.
