modifications of nucleicacids are essential to studies of these molecules for science and applications. Here we report a facile universal approach by harnessing versatile phosphoramidation reactions to regioselectively incorporate alkynyl/azido groups into post-synthetic nucleicacids primed with phosphate at the 5′ termini. With and without the presence of copper, the modified nucleicacids were subjected

The present invention discloses a method of harnessing versatile phosphoramidation reactions to regioselectively incorporate alkynyl/azido groups into post-synthetic nucleic acids primed with phosphate at the 5′ termini. With and without the presence of copper, the modified nucleic acids were subjected to azide-alkyne cycloaddition to obtain various nucleic acid conjugates including a peptide-oligonucleotide conjugate (POC) with a high yield.
