The one-step strategy for the facile syntheses of structurally diverse 1-indanones in moderate to good isolated yields was developed via a ruthenium-catalyzed tandem coupling and cyclization of simple aromatic acids with α,β-unsaturatedketones. The tandem cyclization involves one-pot sequential reactions of C–H activation, conjugate addition, Dieckmann condensation, Michael addition, intramolecular
