Abstract
AbstractCopper‐catalyzed [2+2+1+1] annulation strategy has been investigated for the regioselective synthesis of symmetrical and unsymmetrical 2,6‐diarylpyridines using aliphatic amines as nitrogen source and DMSO as C1‐synthon. The developed protocol was successful for the transformation of non‐activated aromatic ketones and non‐activated aliphatic amines into 2,6‐diarylpyridines via an “easy to access” approach. This protocol has been verified on wide range of substrates having various functional groups.
