Alum-catalyzed one-pot synthesis of dihydropyrano[3,2-b]chromenediones
A simple, green and efficient solventless procedure for the synthesis of eleven dihydropyrano[3,2-b]chromenediones from the three-component condensation reaction of kojic acid, aromatic aldehydes, and dimedone using a reusable alum as catalyst is described.
