  Microwave Enabled Umpulong Mechanism Based Rapid and Efficient Four- and Six-Component Domino Formations of 2-(2′-Azaaryl)imidazoles and anti-1,2-Diarylethylbenzamides

  摘要：

  Concise and efficient six-component and four-component domino approaches to anti-1,2-diarylethylbenzamides and highly Substituted 2-(2'-azaaryl)imidazoles have been developed under solvent-free and microwave-irradiation conditions. The reactions showed a broad scope of substrates in which a wide range of common commercial aromatic aldehydes and heteroaryl nitriles can be used. The syntheses were Finished within short periods (15-34 min) with good to excellent chemical yields and stereoselectivity that avoided tedious workup isolations. New mechanisms involving an umpolung have been proposed for these two reaction processes.
