Amines react with 3-aryl-1--2-propyn-1-ones in three directions, i.e., with addition of the reagent at the triple bond (and the formation of the β-aminovinyl ketone) and intramolecular cyclization leading to the formation of six-membered (flavones) or five-membered (aurones) heterocycles.The development of these reaction paths is controlled by the nature of the amines.Probable reaction paths are proposed.
