Novel N‐aryltriazole nucleosides were synthesized via a Cu‐mediated CN 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, leading to selective N‐arylation of the amide functionality on nucleosides containing both groups on the triazole nucleobase.
