Salicylic acid-catalyzed oxidation of benzylamines and its application in the construction of N-Containing heterocycles. Yields were determined by 1H NMR spectroscopy (isolated yields). (A) Salicyclic acid-catalyzed oxidation of benzylamines to imines. (B) Salicyclic acid-catalyzed oxidative synthesis of benzimidazoles. (C) Application to construct other N-containing heterocycle scaffoids.
