Nucleoside analogues of uridine, 5-bromo-, 5-iodo-, and 5-fluorouridines, thymidine and cytidine were prepared by condensing appropriately substituted 2,4-dimethoxypyrimidines with an acyclic side chain in the form of a benzoylated halo-ether, and subsequent removal of the protecting benzoyl group in base. The 2′-O-p-tosylates of these nucleoside analogues could then be modified to 2′-halo-, azido-
尿苷,5-溴-,5-碘-和5-氟尿苷,胸苷和胞苷的核苷类似物是通过将适当取代的2,4-二甲氧基嘧啶与无环侧链缩合成苯甲酰化卤代醚的形式制备的,随后除去碱中的保护性苯甲酰基。2'- ø - p这些核苷类似物-tosylates然后可以修改成2'-卤代- ,叠氮基,和氨基衍生物。这些化合物中的许多是体外尿苷磷酸化酶的竞争性抑制剂,最活跃的是5-甲基-1-(2'-羟基乙氧基甲基)尿嘧啶。
