discovery of 3′-azido-3′-deoxythymidine (AZT) and 2′,3′-didehydro-2′,3′-dideoxythymidine (d4T) as potent and selective inhibitors of the replication of human immunodeficiency virus (HIV), there has been a growing interest for the synthesis of 2′,3′-didehydro-2′,3′-dideoxynucleosides with electron withdrawing groups on the sugar moiety. Here we described an efficient method for the synthesis of such nucleoside
自从发现 3'-azido-3'-deoxythymidine (AZT) 和 2',3'-didehydro-2',3'-dideoxythymidine (d4T) 作为人类免疫缺陷病毒 (HIV) 复制的有效和选择性抑制剂以来,人们对合成在糖部分具有吸电子基团的 2',3'-didehydro-2',3'-dideoxynucleoside 越来越感兴趣。在这里,我们描述了一种合成具有 AZT 和 d4T 结构特征的核苷类似物的有效方法。关键中间体 3-azido-1,2-bis-O-acetyl-5-O-benzoyl-3-deoxy-D-ribofuranose, 5 由市售的 D-木糖分五步合成,其中一系列嘧啶和嘌呤核苷以高产率合成。使用适当的化学修饰将所得的受保护核苷转化为目标核苷。
