摘要

Indenones are valuable synthetic intermediates for natural products, ligand scaffolds, and material science.[1] Traditional synthetic routes to indenones usually require multiple steps or have limited scope.[2] Transition metal catalyzed approaches have begun to address some of these issues by providing various direct routes for their synthesis.[3, 4] Among these methods, several direct annulation reactions between alkyne and ortho-functionalized ...
