An efficient and green procedure has been developed for the synthesis of hydroxyxanthones from substituted 2,2'-dihydroxybenzophenone precursors via microwave-assisted base-catalyzed cyclization in water. This method provides excellent yields of products in a short time, making it a useful strategy for the synthesis of structurally diverse hydroxyxanthones.
