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.
