Abstrakt: Disodium phosphate catalyzed one-pot synthesis of 3,4-dihydropyrano[3,2-c]chromenes, from aldehydes, active methylene compounds malononitrile and 4-hydroxycoumarin in ethanol:water (1:1) under reflux temperature. The attractive features of this process are inexpensive, efficient, as well as user friendly. [ABSTRACT FROM AUTHOR]
