  Microwave-assisted synthesis of macrocycles via intramolecular and/or bimolecular Ullmann coupling

  摘要：

  Microwave-assisted synthesis of macrocyclic diaryl ethers via intramolecular and/or bimolecular Ullmann coupling is described. Using the optimized conditions, a panel of macrocycles, with different substitution patterns, ring sizes, and linkers, has been successfully synthesized using microwave irradiation. To the best of our knowledge, this work represents the first examples of the microwave-assisted synthesis of macrocyclic diaryl ethers via intramolecular and/or bimolecular Ullmann coupling.

• Inhibitory activity of prostaglandin E2 production by the synthetic 2′-hydroxychalcone analogues: Synthesis and SAR study

  A series of 2'-hydroxychalcones has been synthesized and screened for their in vitro inhibitory activities of cyclooxygenase-2 catalyzed prostaglandin production from lipopolysaccharide-treated RAW 264.7 cells. Structure-activity relationship study suggested that inhibitory activity against prostaglandin E-2 production was governed to a greater extent by the substituent on B ring of the chalcone, and most of the active compounds have at least two methoxy or benzyloxy groups on B ring. The relationship between chalcone structures and their PGE(2) inhibitory activities was also interpreted by docking study on cyclooxygenase-2. (C) 2009 Elsevier Ltd. All rights reserved.
