  Efficient microwave-assisted synthesis and antioxidant activity of 4-arylidene-2-phenyl-1H-imidazol-5(4H)-ones

  摘要：

  AbstractThe efficient synthesis of 4‐arylidene‐2‐phenyl‐1H‐imidazol‐5(4H)‐ones was achieved via microwave‐assisted reactions of 4‐arylmethylene‐2‐phenyloxazol‐5(4H)‐ones with urea in glycol. This approach provides a facile shortcut for the synthesis of this type of compounds with short reaction time, high yields, broad substrate scope and easy operation. Besides, the synthesized compounds were subject to the test of antioxidant activity, which is represented by their capacities for scavenging 1,1‐diphenyl‐2‐picrylhydrazyl, hydroxyl and superoxide anion free radicals. Bioassay of these compounds resulted in the finding of several 4‐arylidene‐2‐phenyl‐1H‐imidazol‐5(4H)‐ones with significant antioxidant activity. J. Heterocyclic Chem., (2012).

  A facile and effective approach for the synthesis of 4-arylidene-2-phenyl-5(4H)-oxazolones has been developed. Under solvent-assisted grinding in the presence of 2,4,6-trichloro-1,3,5-triazine, catalytic triphenylphosphine, and sodium carbonate, dehydration–condensation of hippuric acid with aromatic aldehydes proceeded rapidly within minutes at room temperature to afford the products in good to excellent
