An efficient and direct synthesis of new 2,2'-bipyridine derivatives via microwave-assisted three-component reaction
A series of new 2,2'-bipyridine derivatives were synthesized via three-component reactions of 3-aryl-1-(pyridin-2-yl)prop-2en-1-ones, malononitrile, and aromatic amines in DMF under microwave irradiation. It is an efficient and promising synthetic strategy to construct 2,2-bipyridine skeleton.
