A series of optically pure 1,3-dioxolane nucleoside mimics was synthesized by a synthetic route that allowed incorporation of a 5R-methyl substituent from commercially available starting materials. The pyrrolo[2,3-d]pyrimidine heterocycle was chosen as a substitute for the purine derivative. Coupling of the pyrrolo[2,3-d]pyrimidine and the dioxolane was performed under solid-liquid phase transfer conditions
通过合成途径合成了一系列光学纯的1,3-二氧戊环核苷模拟物,其允许从可商购的原料中引入5R-甲基取代基。选择吡咯并[2,3-d]嘧啶杂环作为嘌呤衍生物的替代物。吡咯并[2,3-d]嘧啶和二氧戊环的偶联在固-液相转移条件下进行。在基于细胞的亚基因组复制子测定中评估了抑制HCV RNA复制的能力。所描述的化合物均未显示出显着的抗HCV活性。
