One-pot cascade reaction of 1-arylpenta-3,4-dien-2-ones with activated ketones including base-promoted Michael addition/intramolecular aldol condensation/copper-catalyzed C–H activation and annulation offers a simple and convenient approach toward dibenzo[b,d]furans. This reaction obviates highly functionalized starting materials and step by step operations and affords products with good efficiency
