The synthesis of several dinucleoside phosphate derivatives which are linked by phosphoramidate bonds [3′-O-P(O)(O−)-NH-5′ or 3′-NH-P(O)(O−)-O-5′] has been accomplished. The internucleoside phosphoramidate linkage was performed using the Staudinger reaction which is directly followed by a Michaelis-Arbuzov type transformation. Due to the exclusive use of base labile blocking groups deprotection could
