A highly regioselective Minisci reaction with the decarboxylative alkylation of purine nucleosides under mild conditions was developed. With 5 mol % AgNO₃ as a catalyst and (NH₄)₂S₂O₈ as an oxidant, a series of purine nucleosides including ribosyl, deoxyribosyl, arabinosyl purine nucleosides worked well with primary, secondary, and tertiary aliphatic carboxylic acids.
