  Fluoronucleosides, Isothiocyanato C-Nucleosides, and Thioureylene Di-C-nucleosides via Cyclic Sulfates

  摘要：

  Cyclic sulfates of N- and C-nucleosides (D-ribo and D-erythro configurations, respectively) are used to prepare T-fluoro and 3'-azido D-xylo N-nucleosides and L-threo C-nucleosides. The reduction of the 3'-azido C-nucleosides (furan, imidazoline-2-thione, and pyrrole derivatives) gives T-amino C-nucleosides, which, by reaction with thiocarbonyldiimidazole, are transformed into T-isothiocyanato C-nucleosides. Reaction of the 3'-amino with the T-isothiocyanato C-nucleosides gives thioureylene di-C-nucleosides, a type of nucleotide analogue with a nonionic bridge isosteric of the phosphate group.
