Some new (2′–5′)triadenylates 13–16, containing at the 2′-terminal end 3′-fluoro-2′,3′-dideoxyadenosine derivatives, have been synthesized by the phosphotriester method. The selectively blocked nucleosides 2, 4, 5, and 7, were synthesized from the corresponding unprotected nucleosides 1, 3, and 6. The synthesized trimers 13, and 14 were 4- and 8-fold, respectively, more stable towards phosphodiesterase
