  Al(OTf)3-Catalyzed Preparation of 4-Hydroxy-3-propargylic ­Coumarins and Subsequent Regioselective Cyclization towards Furo- or Pyrano[3,2-c]coumarins

  摘要：

  An efficient and economical approach to functionalized furo[3,2-c]coumarin and pyrano[3,2-c]coumarin derivatives has been developed from 4-hydroxy-3-(prop-2-ynyl)coumarin derivatives through organocatalysis or metallo-organocatalysis. Selective 5-exo-dig' or 6-endo-dig' cyclization of the 4-hydroxy-3-(prop-2-ynyl)coumarin substrates could be achieved under organocatalytic {1,8-diazabicyclo[5.4.0]undec-7-ene} or metallo-organocatalytic (N-methylmorpholine/CuBr) conditions, respectively, to yield potentially bioactive heterocycles in excellent yields.

  catalyst among the tested ones. The conjugates were evaluated for in-vitro xanthine oxidase activity. The results of the in-vitro assay were quite promising as some conjugates were endowed with remarkable inhibitory potential against the enzyme. HV-8, 11 and 12 were found to be high-potent inhibitors with HV-11 (the most potent inhibitor) possessing an IC50 value of 2.21 µM. The most active conjugate HV-11

  摘要鉴于分子杂交技术在药物设计中的最新成功，本研究设计并合成了2,4-二芳基吡喃并[3,2-c] chromen-5（4H）-作为香豆素和查耳酮的缀合物。 。研究了各种路易斯酸在纯净条件下合成设计的共轭物的催化效率，并优化了SiO2（200-400目）-ZnCl2作为测试催化剂中的最佳催化剂。评价缀合物的体外黄嘌呤氧化酶活性。体外测定的结果非常有前途，因为某些结合物具有明显的抑制酶的潜力。发现HV-8、11和12是高效抑制剂，而HV-11（最有效的抑制剂）的IC50值为2.21 µM。评价活性最高的缀合物HV-11的抑制类型，发现其为混合型抑制剂。还计算了某些选定的共轭物对Lipinski规则的依从性。

Clean reaction, non-chromatographic purification technique, easily accessible reactants, metal and solvent-free and environmentally friendly reaction conditions are the notable advantages of this procedure. In addition, this method possesses lower E-Factors

  A Bi(OTf)3-catalyzed tandem addition/annulation reaction is described in order to synthesize pyrano[3,2-c]coumarins under solvent-free conditions. Substituted/unsubstituted chalcones were conveniently condensed with various 4-hydroxycoumarins by means of this environmentally benign method which produces water as the only side product.
