  Anti-HIV Derivatives of 1-(2,3-Dideoxy-3-N-hydroxyamino-β-D-threo-pentofuranosyl)thymine

  摘要：

  Representative examples of the title compounds including bicyclic analogs (7-9) in which a perhydro-1,3-oxazine is ortho-fused to the furanose ring, have been prepared in good to excellent yields. Compounds 5 and 7 showed marked activity against HIV-1 and HIV-2 replication in CEM cells (50% inhibitory concentration: 0.80-4.3 mu g/mL). Their di-O-acetylated (6) and mono-O-acetylated (8) derivatives were considerably less effective. To the best of our knowledge, these beta-D-threo anti-HIV nucleoside analogs constitute the first examples of anti-HIV active nucleosides bearing this configuration.

  existing strategies toward 3'-hypernucleophilic amine systems do not readily deliver deoxyribo-configured products. We report diastereoselective syntheses of deoxyribo- and deoxyxylo-configured 3'-hydroxyamino- and 3'-methoxyamino-nucelosides from 3'-imine intermediates. The presence or absence of the 5'-hydroxyl-group protection dictates facial selectivity via inter- or intramolecular delivery of hydride

  氨基核苷被用作药物和生物缀合物化学中的关键基序。但是，现有的针对3'-超亲核胺系统的策略不能轻易提供脱氧核糖构型的产品。我们报告了从3'-亚胺中间体的脱氧核糖和脱氧木糖配置的3'-羟基氨基-和3'-甲氧基氨基-noselosides的非对映选择性合成。5'-羟基保护基的存在与否决定了从BH3（硼烷）中氢化物的分子间或分子内递送对面部的选择性。保护基的筛选使人们能够获得一种以前未知的3'-甲氧基氨基-脱氧鸟苷衍生物。
