Transition‐metal‐free regioselective synthesis of functionalizedamino‐indenones by the reaction of ortho‐alkynylaldehydes with a broad range of primary amines by intramolecular cyclization has been described. The designed reaction proceeds through KOH‐mediated Prins‐type cyclization and DMSO‐promoted oxidation of the cyclopent‐2‐en‐1‐one system. The proposed mechanism and role of solvent were well
