## Abstract Novel __N__‐aryltriazole nucleosides were synthesized __via__ a Cu‐mediated Cο£ΏN cross‐coupling reaction, using 3‐aminotriazole acyclonucleosides and various boronic acid reagents. Interestingly, __N__‐arylation proceeded much more rapidly on the amide group than on the amine group, lead
