Acesso em: 7 mar. 2019.2365-6549http://www.repositorio.ufop.br/handle/123456789/11202A 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 FeCl3 as catalyst under aerobic conditions to afford the corresponding 3‐aroylchromanones and tolerates a variety of substituents on both aromatic rings.en-USrestritoChromanonesN,N-dimethylacetamide homoisoflavonoidsArtigo publicado em periodicohttps://onlinelibrary.wiley.com/doi/full/10.1002/slct.201800029https://doi.org/10.1002/slct.201800029
