A novel, one-pot method has been developed for the synthesis of tetrahydrofuro[3,2-c]pyridine-2-carboxylate derivatives via cascade four-component condensation of 6-methyl, 4-hydroxy pyranone, aryl amines, aromatic aldehydes and pyridinium ylide, in presence of triethylamine as a catalyst under ethanol reflux conditions. It affords the corresponding product in high yield (78-92 %) with short reaction time (15-25 min).The anti-inflammatory activity of these compounds was determined. Out of the 17 synthesized compounds, compounds 5j, 5k, 5l, 5m and 5n were excellent inhibitors of TNF-a and IL-6, COX-2, b-glucuronidase.
在乙醇回流条件下,以三乙胺为催化剂,通过 6-甲基、4-羟基吡喃酮、芳基胺、芳香醛和吡啶鎓的级联四组分缩合反应,开发了一种新颖的一锅法合成四氢呋喃并[3,2-c]吡啶-2-甲酸衍生物。这些化合物的抗炎活性得到了测定。在合成的 17 个化合物中,化合物 5j、5k、5l、5m 和 5n 是 TNF-a 和 IL-6、COX-2、b-葡萄糖醛酸酶的极佳抑制剂。
