Modifications of the nucleic acid backbone are essential for the development of oligonucleotide-derived bioactive agents. The NAA-modification represents a novel artificial internucleotide linkage which enables the site-specific introduction of positive c

(Chemical Equation Presented) 5′-Protected 3′-amino-2′, 3′-dideoxynucleosides containing any of the four canonical nucleobases (A/C/G/T) were prepared via azides in five to six steps, starting from deoxynucleosides. For pyrimidines, the synthetic route in

A new method for the synthesis of N3′→P5′ phosphoramidate oligodeoxynucleotides is demonstrated. Described herein is the synthesis of the monomers utilized in the phosphoramidite amine-exchange process and the experimental details pertaining to this new mode of chain assembly. The phosphoramidite amine-exchange method generates coupling yields in the 92-95% range per cycle and further enables the synthesis of chimeric phosphoramidate/phosphodiester or phosphoramidate/ phosphorothioate oligonucleotides with no instrument modifications.
