Preparation of 2′- and 3′-bromo derivatives of 2′,3′-unsaturated uracil and adenine nucleosides has been carried out starting from the corresponding β-hydroxyselenides by way of bromination and successive selenoxide elimination. These compounds have been shown to serve as versatile synthons for the preparation of anti-HIV candidates, 2′-C- and 3′-C-branched 2′,3′-unsaturated nucleosides, through palladium-catalyzed
从相应的β-羟基硒化物开始,通过溴化和相继的亚硒氧化物消除,已经制备了2',3'-不饱和尿嘧啶和腺嘌呤核苷的2'-和3'-溴衍生物。这些化合物已显示出可作为通用合成子,可通过钯催化的交叉偶联和卤素-卤代物制备抗HIV候选物,2'-C-和3'-C支链的2',3'-不饱和核苷。锂交换反应。
