5-(2,2-Difluorovinyl)uracil (IV) was synthesized from 2,4-dimethoxy-5-bromopyrimidine by sequential formylation, difluoromethylenation, and removal of the 2- and 4-methyl groups. Condensation of the trimethylsilyl derivative of IV with protected D-erythro-pentofuranosyl chloride followed by separation of anomers and deblocking gave 5-(2,2-difluorovinyl)-2'-deoxyuridine (V). Compound V was active against
由2,4-二甲氧基-5-溴嘧啶通过顺序甲酰化,二氟甲基化以及除去2-和4-甲基合成5-(2,2-二氟乙烯基)尿嘧啶(IV)。将IV的三甲基甲硅烷基衍生物与保护的D-赤型-呋喃呋喃糖酰氯缩合,然后分离异构体并解封,得到5-(2,2-二氟乙烯基)-2'-脱氧尿苷(V)。化合物V对1型单纯疱疹病毒(HSV-1)感染以及HSV-1胸苷激酶基因转化的肿瘤细胞具有活性。
