  Preparation of novel difluorocyclopropane nucleosides

  摘要：

  Novel difluorinated cyclopropane nucleoside analogues possessing both two vicinal hydroxymethyl groups and a methylene spacer between the base and the ring were synthesized starting from 1,3-dibenzyloxy-2-propanol. After oxidation, olefination, reduction and acetylation the target molecules were obtained by difluoro; cyclopropanation, deacetylation and Mitsunobu reactions followed by two consecutive deprotection steps.
