Abstract New isonucleosides [methyl 5-(1-pyrimidinyl)furanosides] are prepared by nucleophilicopening of the oxetanering of methyl 3,5-anhydro-2-O-(2-fluorobenzyl)-D-xylofuranoside with silylated pyrimidine bases in the presence of trimethylsilyl triflate. Structures, configurations and conformations were determined by NMR techniques and several X-ray diffraction analyses. seven of the isonucleosides
摘要 通过甲基 3,5-脱水-2-O-(2-氟苄基)-D-呋喃木糖苷的氧杂环丁烷环与甲硅烷基化嘧啶碱基亲核开环制备了新的异核苷 [甲基 5-(1-嘧啶基)呋喃糖苷]。三氟甲磺酸三甲基甲硅烷基酯的存在。结构、构型和构象通过核磁共振技术和几种 X 射线衍射分析确定。测试了七种异核苷的细胞毒性和对 HIV、HSV 和其他几种病毒的活性。
