A one step synthesis of the 8-methyl-, 8-ethyl- and 8-vinyl derivatives of adenosine, 2'-deoxyadenosine and 2',3'-dideoxyadenosine starting from the readily available 8-bromo congeners is described. This reaction makes use of a transient silylation procedure and a Pd(0) catalysed cross-coupling with tetraorganotin reagents.

2-, 6-, And 8-alkylated (methyl, ethyl, and vinyl) adenosine analogues were synthesized by a palladium-catalyzed cross-coupling of a tetraalkyltin with the halogenated purine nucleosides.The synthesis of the 8-substituted analogues was accomplished using a transient protection procedure.The 6-alkylated-9-β-D-ribofuranosylpurines as well as 2-ethyladenosine were cytotoxic at relatively low concentrations (0.8-10 μg/mL). 8-Methyladenosine was a potent and selective inhibitor of vaccinia virus, whereas 8-ethyl- and 8-vinyladenosine were specifically inhibitory to respiratory syncytial virus. 8-Vinyladenosine displayed particular activity against herpes simplex virus (type 1).
