Visible light promoted synthesis of dihydropyrano[2,3-c]chromenes via a multicomponent-tandem strategy under solvent and catalyst free conditions

Abstract

The development of unique, mild and efficient one pot, multicomponent-tandem synthesis of highly functionalized dihydropyrano[2,3-c]chromenes under photochemical activation is reported. The key feature of the present work is the utilization of visible light which is a ubiquitous, inexpensive and eco-sustainable reagent for catalysing the reaction. The reported methodology is the first example of visible light induced synthesis of dihydropyrano[2,3-c]chromenes and includes several advantages like solvent and catalyst free, environmentally benign reaction conditions, operational simplicity, cost effectiveness, short reaction times, high atom economy, and excellent yields, making it a genuinely green protocol.
