Palladium-catalyzed cascade reactions of coumarins with alkynes: Synthesis of highly substituted cyclopentadiene fused chromones

The coupling of coumarins with alkynes is described, which proceeds through a palladium-catalyzed cascade sequence. This process provides a new route to the synthesis of highly substituted cyclopentadiene fused chromones.
