  • Alkynyl-2-deoxy-d-riboses, a cornucopia for the generation of families of C-nucleosides
    作者:Mauro F.A. Adamo、Roberto Pergoli、Maria Moccia
    DOI:10.1016/j.tet.2010.09.046
    日期:2010.11
    This study focuses on the preparation of some 1-alkynyl-2-deoxy-d-riboses and their application to the generation of C-nucleosides analogues. Examples are provided in which the alkyne functionality took part in alkylation or cycloaddition reactions. A discussion of the protecting group used is provided.

    [GRAPHICS]The reaction of 3,5-di-O-benzyl-2-deoxy-D-ribofuranose with various alkynyllithium reagents afforded diastereomeric mixtures of the corresponding ring-opened alkynyldiols. The resulting diastereomeric mixtures were successively treated with CO2(CO)(8), a catalytic amount of TfOH, Et3N, and iodine in one pot to give alkynyl C-3,5-di-O-benzyl-2-deoxy-beta-D-ribofuranosides with high beta-selectivities. The cobalt-mediated cyclization (intramolecular Nicholas reaction) is reversible; thus, thermodynamically more stable beta-anomers were obtained preferentially. The alkynyl C-deoxyribofuranosides were converted to a variety of C-deoxyribofuranoside derivatives.
  • Efficient synthesis of fluorescent alkynyl C-nucleosides via Sonogashira coupling for the preparation of DNA-based polyfluorophores
    作者:Dominik K. Kölmel、Luzi J. Barandun、Eric T. Kool
    DOI:10.1039/c6ob01199c
    日期:——
    A facile and general procedure for the preparation of alkynyl C-nucleosides with varied fluorophores is presented. Sonogashira coupling was used as a key reaction to conjugate the dyes to an easily accessible ethynyl functionalized deoxyribose derivative. The new C-nucleosides were used for the preparation of DNA-based polyfluorophores.
