There is disclosed a process for synthesizing 2′-fluoro-2′,3′-dideoxyarabinofuranose derivatives of inosine and adenine on a large scale which involves coupling of a fluorosugar derivative and a purine reactant to provide a purine nucleoside intermediate which is then deoxygenated. 6-Chloro or 6-benzamidopurine and 1,3,5-tri-O-benzoyl-2-deoxy-2-fluoroarabinofuranose are used as starting materials.
揭示了一种合成肌苷和腺嘌呤的2'-氟-2',3'-二去氧阿拉伯呋喃糖衍生物的大规模过程,涉及将氟糖衍生物和嘌呤试剂偶联以提供嘌呤核苷中间体,然后对其进行脱氧。6-氯或6-苯甲酰基嘌呤和1,3,5-三-O-苯甲酰-2-脱氧-2-氟阿拉伯呋喃糖被用作起始物质。
