摘要: 为寻找抗HIV化合物, 们以D-核糖为原料,经甲基化、硅烷基化、还原裂解反应制得重要中间体1-脱氧核糖(5), 再通过形成环状亚砜化合物, NaN3发生反应后,经过还原、缩合、环合、氨化、脱保护基反应制得异脱氧腺嘌呤核苷(1), 各步反应收率均超过70%。其抗HIV活性测定尚在进行中。

Abstract: 1-Deoxyribose (5), prepared from D-ribose via methylation, silylation and reductive cleavage, was converted into cyclic sulfite(7). Reaction of 7 with NaN3 resulted in azide (8), which was converted to the isomeric deoxy adenosine, 4(R)-(6-amino-9H-purin-9-yl)-2(R)-(hydroxymethyl) tetrahy-drofuran-3(R)-ol (1) by a sequence of five high-yield reactions. Antiviral studies are in progress.
