An efficient, practical and atom-efficient method has been developed for the preparation of β-aminoketones and 2,3-dihydroquinazoline-4(1H)-ones via multicomponent one-pot reaction in starch solution as an entirely green catalyst. The advantages of this novel protocol are high yields, short reaction time, simple methodology, easy work-up and purification, lack of toxicity and eco-friendly catalyst. .
