Reaction of 9-[3, 5-di-O-(tetrahydropyran-2-yl)-β-D-arabinofuranosyl]uracil (2) with diethylaminosulfur trifluoride in the presence of pyridine afforded 2'-deoxy-2'-fluororiboside 3a, from which 2'-deoxy-2'-fluorocytidine (4b) has been synthesized in good yield. Compound 3a was deprotected and subsequently treated with various benzyl halides or 2-chloro-4-fluoroacetophenone to give corresponding N3-substituted 2'-deoxy-2'-fluorouridines 5a-c and 6. Compounds 5a-c, as well as 6, showed weak hypnotic activity in mice. Compound 4b showed moderate antiviral activity against human immunodeficiency virus-1 but 3b, 5a-c, and 6 were virtually inactive.
9-[3, 5-二-O-(四氢吡喃-2-基)-β-D-阿拉伯呋喃糖基]尿嘧啶 (2) 与二乙氨基三氟化硫在吡啶存在下反应,得到 2'-脱氧-2'-氟核苷 3a ,由此以良好的产率合成了 2'-脱氧-2'-氟胞苷 (4b)。将化合物3a脱保护,随后用各种苄基卤或2-氯-4-氟苯乙酮处理,得到相应的N3-取代的2'-脱氧-2'-氟尿苷5a-c和6。化合物5a-c以及6,对小鼠表现出较弱的催眠活性。化合物4b对人类免疫缺陷病毒1表现出中等的抗病毒活性,但3b、5a-c和6实际上没有活性。
