Resumen:
A simple and clean procedure for the preparation of functionalized flavones and chromones using commercial Keggin heteropolyacid in acetonitrile medium is described for the cyclization of 1-(2-hydroxyaryl)-3-aryl-1,3-propanodiones. Sixteen examples are reported, yields ranging in 60-91%; five substituted 2-naphthylchromones are prepared for the first time.
