[A convenient approach to the synthesis of the phosphoramidite non-nucleotide monomers for the preparation of functionalized oligonucleotide derivatives].

Abstract

A simple approach to the synthesis of phosphoramidite synthons for non-nucleotide inserts using 4-(2-(4,4'-dimethoxytrityloxy)ethyl)morpholine-2,3-dione as a key precursor is suggested. Using the method developed various inserts have been introduced into oligonucleotides to obtain intercalator-containing (acridine) as well as branched oligonucleotides.
