Copper-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-diarylpyridinesviaan easy to access approach. This protocol has been verified on wide range of substrates having various functional groups.
