1,3-dicarbonyl compounds and methyl ketones or terminal aryl alkenes as simple and readily available starting materials can be efficiently converted to unsymmetrical 1,4-enediones under mild reaction conditions using a focusing domino strategy. The reaction allows an operationally simple, straightforward synthesis of various unsymmetrical 1,4-enediones.
