AerobicoxidativeCHfunctionalization of primary aliphatic amines has been accomplished with a biomimetic cooperative catalytic system to furnish 1,2‐disubstituted benzimidazoles that play an important role as drug discovery targets. This one‐pot atom‐economical multistep process, which proceeds under mild conditions, with ambient air and equimolar amounts of each coupling partner, constitutes a
The benzimidazole ring of the heterocyclic pharmacophores is one of the most widespread and studied systems in nature. The benzimidazolederivativesynthesis study is a crucial point for the development of a clinically available benzimidazole-based drug. Here, we report a simple microwave assisted method for the synthesis of 1,2-disubstituted benzimidazoles. The combination of the molar ratio of N
