Condensation of aldehydes with 1,3-dicarbonyl compounds such as 2,4-pentanedione (2), ethyl 2-chloro-3-oxobutanoate (4), 3-chloro-2,4-pentanedione (5), and α-acetyl-γ-butyrolactones, catalyzed by potassium carbonate proceeded via deacylation under mild conditions to give α,β-unsaturated ketones and esters in one step.
