Bio-compatible eutectic mixture for multi-component synthesis: A valuable acidic catalyst for synthesis of novel 2,3-dihydroquinazolin-4(1H)-one derivatives
Novel derivatives of quinazolin-4(1H)-one derivatives were effectively synthesized via one-pot multi-component reaction of isatoic anhydride, aldehyde and aromatic amines using acidic catalyst in methanol. The catalyst, being a deepeutectic mixture of choline chloride and malonic acid, gave better results than several reported catalysts. Moreover, such eutectic mixtures are cost-effective, recyclable
