chemically been combined with the appropriately protected (2′–5′)diadenylate 20 by the phosphotriester approach to give the 2′–5′ oligonucleotide trimers 21–24. The deprotection of the various blocking groups by chemical means afforded the 2′–5′ trimers 25–28, which can be regarded as new type of a potential prodrug form delivering nucleotides to the targets inside cells. In an analogous series of reactions
