A simple and straightforward synthesis of 3‐aroylchromanones based on a tandem iron catalyzed α‐methylenation – intramolecular oxy‐Michael addition reaction of dibenzoylmethanes with N,N ‐dimethylacetamide is described. The reaction employs FeCl 3 as catalyst under aerobic conditions to afford the corresponding 3‐aroylchromanones and tolerates a variety of substituents on both aromatic rings.
