The configuration of the duplex stabilising 3′-C-P-N-5′ ethyl phosphonamidate nucleic acid backbone modification has been identified as R P following the preparation of cyclic nucleoside analogues and NOF studies. Complimentary routes for formation of the key phosphonamidate nitrogen to phosphorus bond from stereochemically defined H-phosphinate intermediates, involving both a retention and inversion at the phosphours centre, have been identified.
