1,5‐di‐O‐acetyl‐2,3‐dideoxy‐3‐phthalimido‐β‐D‐erythro‐pentofuranose (1) with silylated pyrimidinediones 2a–c using the Lewis acid trimethylsilyl triflate as catalyst afforded nucleosides 3a–c and 4a,c which were deprotected with 33% methylamine/ethanol to give the corresponding 3‐aminonucleosides 5a–c and 6. These were reacted with 1,4‐dinitroimidazoles 7a,b to give the 3‐imidazolyldideoxynucleosides
1,5-di-O-acetyl-2,3-dideoxy-3-phthalimido-β-D-erythro-pentofuranose (1) 与甲硅烷基化嘧啶二酮 2a – c 使用路易斯酸三甲基甲硅烷基三氟甲磺酸酯作为催化剂反应得到核苷 3a– c 和 4a、c 用 33% 甲胺/乙醇脱保护得到相应的 3-氨基核苷 5a-c 和 6。这些与 1,4-二硝基咪唑 7a、b 反应得到 3-咪唑基二脱氧核苷 8a、b 和 9a -F。在亚毒性浓度下,这些化合物对 HIV-1 无效。
