A practical and efficientsynthesis of various 1,2,5-tricarbonyl compounds is described. The synthesis has been carried out by a conjugate addition of methyl cyanoacetate to the β-position of α,β-unsaturated carbonyl compounds and a subsequent copper(I) iodide-catalyzed aerobicoxidation. In addition, various α-aryl- and α-alkyl-α-keto esters have been synthesized using a similar approach.
