An efficient avenue for the direct N-arylation of nucleobases with arylboronicacids that is catalyzed by simplecoppersalts was discovered. The N-arylnucleobases were obtained in excellent yields at room temperature within 45 min when methanol and water were used as a mixed solvent. Under these conditions, the couplingreaction tolerates both electron-donating and electron-withdrawing substituents
A Mild and Efficient Method for<i>N</i>‐Arylnucleobase Synthesis<i>via</i>the Cross‐Coupling Reactions of Nucleobases with Arylboronic Acids Catalyzed by Simple Copper Salts
A simple and efficient copper-salt catalyzed N-arylation of nucleobases is reported. In a mixed solvent of MeOH and H2O, the coupling products were obtained in moderate to excellent yields at room temperature within a short time. A variety of substituted N-aryl nucleobases can be prepared through this procedure.
