Ethyl 4-oxo-2-alkenoates and 1,4-dioxo-2-alkenes are easily prepared by treating ethyl 4-hydroxy-2-alkynoates and 4-hydroxy-2-alkyn-1-ones with n-tributylamine. Treatment of ethyl 4-hydroxy-2-alkynoates and 4-hydroxy-2-alkyn-1-ones with palladium-tributylammonium formate produces ethyl 4-oxo-alkanoates and 1,4-alkandiones in good to high yield through a novel one-pot isomerization/hydrogenation reaction
