摘要：
The chalcones: 1-(2-hydroxy phenyl)-3[3-(aryl)-1-phenyl-1H-pyrazol-4-yl]-propenones (la-h) were subjected to oxidation with CuBr(2) in DMSO or Hg(OAc)(2) in pyridine under microwave irradiation and also under conventional heating to afford 5-substituted 2-((3-aryl)-1-phenyl-1H-pyrazol-4-yl-methylene)-benzofuran-3-ones (aurones) (lla-h) in excellent yields.
