  Design, synthesis, and biological evaluation of novel iso-d-2′,3′-dideoxy-3′-fluorothianucleoside derivatives

  摘要：

  Novel iso-D-2',3'-dideoxythianucleoside derivatives 1-4 were designed and asymmetrically synthesized as a bioisostere of lamivudine to search for new anti-HIV agents. The information about using sulfur participation occurred on DAST fluorination and Mitsunobu reaction will be of great help in synthesizing sulfur-containing compounds. Final compounds 1-4 were evaluated against HIV-1 and 2, HSV-1 and 2, EMCV, Cox. B3, VSV, FluA (Taiwan), FluA (Johan.), FCV, and FIR Only cytosine analogue 3 showed a potent anti-VSV activity (EC50 = 9.43 mu g/mL). This result implies that iso-2',3'-dideoxy sugar templates might play a role of a sugar surrogate of nucleosides for the development of anti-RNA virus agent. (c) 2006 Elsevier Ltd.

  antimetabolites, specifically several 2'-modified 2'-deoxy-4'-thiocytidines, were synthesized as potential new antineoplastic agents. Methyl 3-O-benzylxylofuranoside was converted to a 1,4-anhydro-4-thioarabitol 24. Protection of the primary alcohol of 24 gave a common intermediate (15) which was useful for the synthesis of various 2'-modified 2'-deoxy-4'-thionucleosides. Oxidation of the secondary hydroxyl

  Novel isoD-2',3'-dideoxythianucleoside derivatives 1-3 were designed and asymmetrically synthesized to search for new anti-HIV agents. Final compounds 1-3 were evaluated against a variety of viruses including HIV-1 and 2. Only cytosine analog 3 showed a potent anti-VSV activity (EC50 = 9.43 mu g/mL). This result implies that iso 2',3'-dideoxy sugar templates might play a role of a sugar surrogate of nucleosides for the development of anti-RNA virus agent.
• Synthesis of Novel Iso-4‘-thionucleosides Using the Mitsunobu Reaction
  作者：Kohei Yamada、Shinji Sakata、Yuichi Yoshimura

  日期：1998.10.1

  A novel class of isomeric 4'-thionucleosides with the base moiety at the 2'-position was synthesized from D-glucose. The coupling of 1,4-anhydro-4-thioarabitol (13) with various nucleobases using the Mitsunobu reaction was investigated. With both purines and N-3-benzoyluracils, the reaction predominantly gave beta-isomers, suggesting that these were produced via an episulfonium intermediate. The beta-anomers produced by the reaction of N-3-benzoyluracils included both N- and O-alkylated derivatives. Interestingly, only the reaction of N-3-benzoyluracil gave a mixture of N-alkylated adduct (20d) and O-alkylated bipyrimidinyl adduct (22), the structure of which was unambiguously determined by NMR spectroscopic data including HMBC and NOE. Deprotection of the Mitsunobu reaction products gave the desired iso-4'-thionucleosides.
