′-seco acyclic nucleosides (4–14) were prepared by nucleophilic substitution of protected pyrimidine bases on ethyl 3,3-diethoxypropanoate (3). Structures were characterized spectroscopically and a brief analysis of their conformation in solution was performed by the vicinal coupling constants 3 J H2′ aH3′ and 3 J H2′ bH3′. In solid state, compound 6 forms a homodimer linked by hydrogen bonding. In preliminary
通过在 3,3-二乙氧基丙酸乙酯 (3) 上对受保护的嘧啶碱基进行亲核取代,制备了 11 个新的 3',4'-seco 无环核苷 (4-14)。通过光谱学表征结构,并通过邻位耦合常数 3 J H2' aH3' 和 3 J H2' bH3' 对其在溶液中的构象进行简要分析。在固态下,化合物 6 形成通过氢键连接的同型二聚体。在初步测试中,所有化合物在体外均对 HIV-1 RT 表现出低毒性和温和的活性。
