Methyl 2,3-dideoxy-3-fluoro-5-O-(4-phenylbenzoyl)-β-D-erythro-pentofuranoside was condensed with trimethylsilylated 5-substituted uracils to give nucleosides using trimethylsilyl trifluoromethanesulfonate as catalyst. In the case of 5-nitrouracil an acyclic nucleoside believed to be an intermediate for the corresponding nucleoside was isolated. The 5-substituents were selected from neural network calculations on compounds with potential activity against HIV-1. All compounds from the condensation reactions were deacylated by treatment with sodium methoxide in methanol.
以三氟甲磺酸三甲基硅酯为催化剂,将 2,3-二脱氧-3-氟-5-O-(4-苯基苯甲酰基)-δ-D-赤式戊呋喃糖苷与三甲基硅烷化的 5-取代尿嘧啶缩合,得到核苷。在 5-硝基尿嘧啶的情况下,分离出了一种无环核苷,据信它是相应核苷的中间体。 5 取代基是从对 HIV-1 有潜在活性的化合物的神经网络计算中选出的。缩合反应产生的所有化合物都在甲醇中用甲醇钠进行了脱乙酰处理。
