Starting from substituted alkynones, α-pyrones and/or 1H-pyridines were generated in a Michael addition–cyclocondensation with ethyl cyanoacetate. The peculiar product formation depends on the reaction conditions as well as on the electronic substitution

Aroylphenylacetylenes (Ia-c) react with ethyl cyanoacetate and ethyl acetoacetate in the presence of sodium ethoxide to give the corresponding 3-cyano-4,6-diaryl-2H-pyran-2-ones (IIIa-c) and 4,6-diaryl-2H-pyran-2-ones (IVa-c), respectively.On the other ha
