A metal-free and light-promoted approach to the synthesis of N-9 alkylated purine nucleoside derivatives, via a CF₃ radical triggered radical relay pathway, has been developed. Purine nucleoside derivatives were prepared regioselectively in good to high yields. Photosensitizers and metals are free in this transformation. Visible light or even sunlight can be used as the source of light for the reactions.
