Synthesis of amide-linked [(3')CH2CO-NH(5')] nucleoside analogues of small oligonucleotides

Nucleosides Nucleotides Nucleic Acids. 2000 Jan-Feb;19(1-2):69-86. doi: 10.1080/15257770008032997.

Abstract

We report syntheses of new amide-linked (di-penta)nucleoside analogues of antisense oligonucleotide components. Solution-phase coupling of 3'-(carboxymethyl)-3'-deoxy- and 5'-amino-5'-deoxynucleoside derivatives provides amide dimers. Activated [3'-(carboxymethyl)-3'-deoxy] units with a 5'-azido-5'-deoxy function provide "masked" 5'-amino-5'-deoxy residues for chain extension, and a 5'-O-DMT-protected unit provides the 5'-terminus for attachment to a phosphodiester linkage.
