uracil (7) with propargyl alcohol to afford 8 which was fluorinated to give the fluoro propargyl derivative 9. Compound 7 was synthesized by N1‐alkylation of the corresponding uracil. Significant activity was found against HIV‐1 except for compounds with 5‐hydroxymethyl and 5‐fluoromethyl substituents.
6-苄基-5-羟甲基尿嘧啶(1)与甲醛缩醛偶联,然后使用(二乙氨基)三氟化硫(DAST)进行氟化,得到1-烯氧基甲基和1-炔丙氧基甲基5-氟甲基-6-苄基尿嘧啶3a-c。6-(3,5-二甲基苄基)-5-乙基-1-[(2-氟乙氧基)甲基]嘧啶-2,4(1H,3H)-二酮(6)通过相应的羟基衍生物5的氟化合成。 6-(3,5-二甲基苄基)-5-乙基-1-(4-碘苄基)尿嘧啶(7)与炔丙醇发生Sonogoshira反应,得到8,氟化得到氟炔衍生物9。化合物7为通过相应尿嘧啶的 N1-烷基化合成。除了具有 5-羟甲基和 5-氟甲基取代基的化合物外,发现对 HIV-1 具有显着活性。
