New oxime-containing acyclic nucleoside phosphonates 9-2-[(phosphonomethyl)oximino]ethyl}adenine (1), -guanine (2) and 9-2-[(phosphonomethyl)oximino]propyl}adenine (3) with wide spectrum activity against different types of viruses were synthesized. The key intermediate, diethyl aminooxymethylphosphonate, was obtained by the Mitsunobu reaction. Modified conditions for the by-product separation (without
新的含肟的无环核苷膦酸酯9- 2-[(膦酰基甲基)肟基]乙基}腺嘌呤(1),-鸟嘌呤(2)和9- 2-[(膦酰基甲基)肟基]丙基}腺嘌呤(3)宽合成了针对不同类型病毒的光谱活性。通过Mitsunobu反应获得关键的中间体氨基乙基氧甲基膦酸二乙酯。改进的副产物分离条件(无需色谱和蒸馏)可使我们获得85%的氨氧基中间体收率。DBU和Cs 2 CO 3对N 9 / N 7的影响研究了腺嘌呤和鸟嘌呤烷基化的产物比。发现了一种方便的氨氧基检测方法。测试了合成的膦酸酯,它们似乎显示出对不同类型病毒(HIV,细胞培养中的疱疹病毒和复制子系统中的丙型肝炎病毒)的中等活性,毒性高达1000μM。
