3'-Deoxy-3'-(1, 2, 3-triazol-1-yl)thymidines (5a, 6a, 8a, 11a, and 12a) and 2', 3'-dideoxy-3'-(1, 2, 3-triazol-1-yl)uridines (5a, 6b, 8b, 11b, and 12b) were synthesized as cyclic analogues of 3'-azido-3'-deoxythymidine (AZT) and 3'-azido-2', 3'-dideoxyuridine (CS-87) by the cyclization of 5'-trityl derivatives (1a, b) of AZT and CS-87 using α-ketophosphorus ylides and with acetylenic compounds followed by deprotection of the 5'-trityl group. It was hypothesized that the triazole nitrogen atoms could mimic and distorted azido group. However, no significant activity against human immunodeficiency virus type 1 (HIV-1) was observed with any of these compounds. 5'-Triphosphates (17a and 18a, b), prepared from 5a and 6a, b, were inactive against HIV-1 and Rausher murine leukemia virus (RLV) reverse transcriptases.
用α-酮磷酸盐环化 AZT 和 CS-87 的 5'-三苯甲基衍生物(1a,b),合成了 3'-脱氧-3'-(1,2,3-三唑-1-基)胸苷(5a,6a,8a,11a 和 12a)和 2',3'-二脱氧-3'-(1,2,3-三唑-1-基)尿苷(5a,6b,8b,11b 和 12b),作为 3'-叠氮-3'-脱氧胸苷(AZT)和 3'-叠氮-2'-脱氧尿苷(CS-87)的环状类似物、和 CS-87 的 5'-三苯甲基衍生物(1a、b)通过α-酮磷酰化物和乙炔化合物环化,然后对 5'-三苯甲基基团进行脱保护,合成了 3'-叠氮-3'-脱氧胸苷(AZT)和 3'-叠氮-2',3'-二脱氧尿苷(CS-87)的环状类似物。据推测,三唑的氮原子可以模拟和扭曲叠氮基团。然而,这些化合物对人体免疫缺陷病毒 1 型(HIV-1)都没有明显的活性。由 5a 和 6a b 制备的 5'- 三磷酸酯(17a 和 18a, b)对 HIV-1 和 Rausher 小鼠白血病病毒(RLV)逆转录酶没有活性。
