  Synthesis and anti-inflammatory activity of benzophenone analogues

  摘要：

  A series of substituted benzophenone analogues has been synthesized and evaluated as orally active anti-inflammatory agents with reduced side effects. The anti-inflammatory and ulcerogenic activities of the compounds were compared with naproxen, indomethacin, and phenylbutazone. In carrageenan-induced foot pad edema assay, benzophenone analogues showed an interesting anti-inflammatory activity. In the air-pouch test, some of the analogues reduced the total number of leukocytes of the exudate, which indicates inhibition of prostaglandin production. Side effects of the compounds were examined on gastric mucosa, in the liver and stomach. None of the compounds showed significant side effects compared with nonsteroidal anti-inflammatory drugs such as indomethacin and naproxen. (C) 2004 Elsevier Inc. All rights reserved.

  enzene. Acid fluorides were converted into acylphosphine sulfides and thioesters using diphosphine disulfides and disulfides/triphenylphosphine, respectively. Aryl esters were obtained from acid fluorides and phenols in the presence of triphenylsilane. Aryl esters, acylphosphine sulfides, and thioesters were also interconverted in the presence of rhodium complexes. These rhodium-catalyzed acyl transfer

  铑/膦配合物催化酰基氟，芳基酯，酰基膦硫化物和硫代酯之间的平衡酰基转移反应。使用合适的共底物来接受杂原子基团将平衡转移到所需的产物上。使用苯甲酰基五氟苯作为氟化物供体，将酰基膦硫化物和芳基酯转化为酰基氟，并使用（4-甲苯基硫代）五氟苯进行硫酯的氟化反应。分别使用二膦二硫化物和二硫化物/三苯基膦将酰氟转化为酰基膦硫化物和硫酯。在三苯基硅烷的存在下，由酰基氟和苯酚获得芳基酯。在铑配合物的存在下，芳基酯，酰基膦硫化物和硫代酯也可以相互转化。这些铑催化的酰基转移反应在中性条件下进行，无需使用酸或碱。羰基铑中间体参与这些反应是由硫代酯和炔烃的羰基硫化反应提示的。

  Fluorous Yamaguchi (FY) reagents bearing a perfluoroalkyl chain were prepared and employed in esterification reactions; the yields were similar to those obtained with the traditional Yamaguchi (TY) reagent. Fluorous benzoic acids derived from the FY reagents were separated easily after the reaction. GC analysis revealed that the initial rates of reaction with the FY reagents were higher than those with
