  2,5-Diarylisothiazolone: novel inhibitors of cytokine-induced cartilage destruction

  摘要：

  A series of 2,5-diarylisothiazolones is reported that inhibit the IL-lp-induced breakdown of bovine nasal septum cartilage in an organ culture assay. The synthesis and preliminary SAR of these compounds are described. These compounds represent a novel, nonpeptide lead series approach to the mediation of the chronic cartilage breakdown associated with arthritic disease. These compounds are relatively resistant to reductive metabolism by liver microsomal preparations and appear to inhibit cartilage breakdown by interfering with the proteolytic activation of matrix metalloproteinases.

  Abstract A new method for the synthesis of 3-thioazaspiro[4,5]trienones was developed using Pd nanoparticle catalysts, which are highly efficient, environmentally friendly and recyclable. Alkynes and thiophene phenols are effectively cyclized by Pd/ZrO2 catalyst under visible light irradiation. The present protocol simply utilizes visible light as the safe and ecofriendly energy source, and the Pd/ZrO2

  A thioannulation of propynamides with sodium sulfide and CH2Cl2 in the absence of transition-metal and base has been established. This one-pot tandem reaction provides a facile and efficient method for the selective synthesis of 1,3-thiazide-4-ones or thiazolidine-4-ones through constructing both C–N and C–S bonds. The atom-economic reaction features mild conditions and good functional group tolerance

  A copper‐catalyzed difunctionalizing trifluoromethylation of activated alkynes with the cheap reagent sodium trifluoromethanesulfinate (NaSO2CF3 or Langlois’ reagent) has been developed incorporating a tandem cyclization/dearomatization process. This strategy affords a straightforward route to synthesis of 3‐(trifluoromethyl)‐spiro[4.5]trienones, and presents an example of difunctionalization of alkynes

  An efficient and facile method for the preparation of alkynamides through Et3N-catalyzed alumination of alkyl- or aryl-substituted terminal alkynes with AlMe3 and sequential nucleophilic addition of in situ generated alkynylaluminums to isocyanates is described. This method has the merits of using readily available isocyanates and monosubstituted alkynes, easy access to organoaluminums, short reaction

  The reaction of 3-aryl-N-(aryl)propiolamides with arenes in TfOH at room temperature for 0.5 h led to 4,4-diaryl-3,4-dihydroquinolin-2-(1H)-ones in yields of 44-98%. The obtained dihydroquinolinones were further transformed into the corresponding N-acyl or N-formyl derivatives. For the latter, the superelectrophilic activation of the N-formyl group by TfOH in the reaction with benzene resulted in the

  3-芳基-N-（芳基）丙酰胺与芳烃在TfOH中于室温下反应0.5小时，得到4,4-二芳基-3,4-二氢喹啉-2-（1H）-酮，产率为44-98 ％。将获得的二氢喹啉酮进一步转化为相应的N-酰基或N-甲酰基衍生物。对于后者，在与苯的反应中，TfOH对N-甲酰基的超亲电活化导致形成N-（二苯甲基）-取代的二氢喹啉酮。
