A series if 2',3'-dideoxy-3'-C-hydroxymethyl purine nucleosides were prepared based on the photochemical ring expansion of a chiral cyclobutanone precursor, (2S)-trans-2,3-bis[(benzoyloxy)methyl]cyclobutanone, in the presence of a 6-substituted purine. Both alpha- and beta-anomers are produced in this transformation. Deprotection was effected by reaction of the photoadducts with saturated methanolic
基于手性环丁酮前体(2S)-反式2,3-双[(苯甲酰氧基)甲基]的光化学扩环,制备了一系列2',3'-二脱氧-3'-C-羟甲基嘌呤核苷环丁酮,在6-取代的嘌呤存在下。在这种转化中,α-和β-端基异构体均产生。通过光加合物与饱和甲醇氨的反应进行脱保护。测试了九种嘌呤核苷对HIV IIIB病毒对H9细胞的抑制作用。6-己氧基和腺嘌呤衍生物4e,c似乎在抑制病毒繁殖方面最有效,而4c的活性与ddI和AZT相当。
