This invention relates to a process for the synthesis of ketomethylene derivatives of the tripeptide Phe-Gly-Pro (“keto-ACE”, compound 5
a
) and analogues thereof. The synthesis process proceeds via an α,β-unsaturated keto intermediate. A key feature of the process involves a Horner-Emmons olefination of the, -unsaturated keto-phosphonate with ethyl glyoxylate. Keto-ACE analogues produced by the process of the invention display C-domain selectivity.
