The synthesis of γ,δ-unsaturated-β-keto esters was achieved by the Lewis acid-catalysed direct CH insertion of an α-diazoester into various α,β-substituted-unsaturated aldehydes. CH insertion of ethyl diazoacetate into alkyl- and aryl-substituted α,β-unsaturated aldehydes was performed under mild conditions to afford the corresponding γ,δ-unsaturated-β-keto esters in moderate to high yields as a mixture of keto/enol tautomers.
