Arylmethyl halides are readily synthesized via halogenation from the basic raw materials, even in green processes. They are used to replace their downstream products to prepare medicinally important 2‐aryl benzimidazoles. CuBr‐catalyzed synthesis of 2‐aryl benzimidazoles from arylmethyl halides and 1,2‐diaminoarenes via a one‐pot domino reaction is developed. This new synthetic method is simple, practical...
Many synthetic methods of racemic N-aryl (including N-(2-haloaryl)) α-amino acid amides have been reported, but there are only a few for eutomers and none for inactivated halo(hetero)arenes. Selective C–N coupling of aliphatic amino group of α-amino acid amides is a direct and valuable method, but still unresolved. Here we disclose a simple and cheap ligand-free CuI-catalyzed selective synthesis of...
