An efficient synthesis of new khellactone-type compounds using potassium hydroxide as catalyst via one-pot, three-component reaction

In the present work, three-component synthesis for novel khellactone-type compounds via the reaction of Meldrum's acid, aryl aldehydes and 5,7-dihydroxy benzopyrone derivatives was described. In this reaction 10-aryl substituted-9,10-dihydropyrano[2,3-h]benzopyrone-8-ones as new khellactone analogous in the presence of catalytic amount of potassium hydroxide as cheap and green basic catalyst were obtained in good to excellent yields under refluxing methanol.
