efficient synthesis of 2'-O-substituted ribonucleosides, including 2'-O-TBDMS and 2'-O-TOM protected as well as 2'-O-Me and 2'-O-allyl derivatives is presented. Di-t-butylsilylene group was employed for simultaneous protection of 3'- and 5'- hydroxyl functions of nucleoside on the first step. Subsequent silylation or alkylation of free 2'-OH followed by introduction of suitable protection on the base
提出了2'-O-取代的核糖核苷的有效合成方法,包括2'-O-TBDMS和受保护的2'-O-TOM以及2'-O-Me和2'-O-烯丙基衍生物。第一步,使用二叔丁基亚甲硅烷基同时保护核苷的3'-和5'-羟基官能团。随后将游离的2'-OH进行甲硅烷基化或烷基化,然后在碱基部分上引入合适的保护基,并除去环状甲硅烷基保护基,从而以高收率得到目标化合物。
