General description

5′-O-(4,4′-Dimethoxytrityl)thymidine is a pyrimidine.

Application

5′-O-(4,4′-Dimethoxytrityl)thymidine may be used in the stereoselective synthesis of 3′-deoxy-3′-threo-hydroxymethyl nucleoside, which can be subsequently incorporated into oligodeoxynucleotides. It may be used as research tool for antiviral and anticancer studies.

A novel solid-phase synthesis of 5'-radiolabeled oligonucleotides is described. The labeling reaction is carried out by the phosphoramidite method with the aid of [4,6-di-14C]-5'-dimethoxytritylthymidine building block 1. The feasibility of the method is demonstrated by preparation of 3'-phosphorylated dodecathymidylate phosphorothioate
