Unnatural nucleoside analogues are valuable research and clinical tools as antiproliferative, antibacterial or antiviral agents. In this context, clevudine (L-FMAU), a reverse transcriptase inhibitor, is currently used for the treatment of the hepatitis B virus. Herein, we describe a new strategy for the preparation of clevudine. Starting from 2-deoxy-2-fluoro-D-galactopyranose, we developed the shortest
非天然核苷类似物作为抗增殖、抗菌或抗病毒剂是有价值的研究和临床工具。在此背景下,逆转录酶抑制剂克拉夫定 ( L- FMAU) 目前用于治疗乙型肝炎病毒。在此,我们描述了一种制备克拉夫定的新策略。从 2-脱氧-2-氟-D-吡喃半乳糖开始,我们开发了这种非天然L-核苷的最短和最高产率的合成。关键步骤涉及碘促进的环化和氧化裂解以获取L -阿拉伯呋喃糖支架。
