A simple protocol for the efficient synthesis of dihydropyrano[3,2-c]chromene derivatives has been achieved by refluxing aromatic aldehydes, malononitrile, 4-hydroxycoumarin and 4-chlorophenylboronic acid. Particularly valuable features of this method include satisfactory yields of products and short reaction time
