The reaction of β-keto amides with ethyl(iodomethyl)zinc provides access to a wide variety of γ-keto amides, including primary, secondary, and tertiary amides. Although the reaction of α-substituted β-keto amides are in many cases unsatisfactory, the method can be applied to a broad spectrum of substrates that possess imide and olefinic functionality.

Organolithium and Grignard reagents react with the readily-formed irontetracarbonylcomplexes of α,β-unsaturated amides to give γ-ketoamides in good yield acyl transfer from the metal to the β carbon of the α,β-unsaturated amide.
