Synthesis of several 5‐substituted (2′S)‐2′‐deoxy‐2′‐C‐methylcytidines (8) and ‐uridines (6, 11) has been accomplished using radical deoxygenation of the 2′‐tert‐alcohols via their methyl oxalyl esters as a key reaction. Anti‐herpes simplex virus type‐1 and ‐2, and anti‐varicella‐zoster virus activities of the newly synthesized nucleosides were evaluated. Among them, the 5‐iodouracil derivative 6e
几个 5-取代 (2'S)-2'-脱氧-2'-C-甲基胞苷 (8) 和 -尿苷 (6, 11) 的合成已通过 2'-叔醇的自由基脱氧完成甲基草酸酯作为关键反应。评估了新合成的核苷的抗单纯疱疹病毒 1 型和 2 型以及抗水痘带状疱疹病毒的活性。其中,5-碘尿嘧啶衍生物6e对1型单纯疱疹病毒的活性最强,EC50为0.14 μg/mL,无细胞毒性,高达100 μg/mL,但对单纯疱疹病毒型活性较弱-2 并且在体外对高达 50 μg/mL 的水痘-带状疱疹病毒没有活性。尽管 5-氟胞嘧啶衍生物 8b 具有有效的抗单纯疱疹病毒 1 型活性(EC50 = 0.22 μg/mL),
