An efficient synthetic protocol of microwave-assisted synthesis of some novel 2-(3-aryl,1-phenyl-1H-pyrazol-4-yl)-8H-pyrano[2,3-f]chromen-4-ones 6a–j in excellent yields starting from 3-(3-aryl,1-phenyl-1H-pyrazol-4-yl)-1-(5-hydroxy-2H-chromen-6-yl)-propenones 5a–j was described. This approach offers the advantages of short reaction time (3–5 min), mild(More)
An efficient microwave-assisted method of synthesis of some novel 2-arylidene-2H-furo[2,3-f]chromen-3(7H)-ones 6a–j in excellent yields was described and structural assignment of the products was confirmed on the basis of IR, 1H NMR, 13C NMR, MS, and analytical data. The synthesized compounds were screened for antioxidant activity using(More)
