A new linker group for functionalization of nucleic acids

Abstract

A new linker bearing two orthogonal precursor groups - an amino group for the reaction with electrophilic agents, and also a terminal triple bond for the reaction with an aliphatic azido group (1,3-dipolar cycloaddition reaction) for the introduction of the different residues into nucleosides is designed and synthesized. 5'-Triphosphates of various nucleosides bearing proposed linker group have been obtained.
