Ultrasound Promoted Green and Facile One-Pot Multicomponent Synthesis of 3,4-dihydropyrano[c]chromene Derivatives
Ultrasound promoted mild one-pot multicomponent synthesis of 3,4-dihydropyrano[c]chromenes from 4-hydroxycoumarin, arylaldehydes and malononitrile was achieved in aqueous media. The methodology promises advantages of short reaction times, environmentally benign conditions, high yields, and operation...
