This invention relates to a process for the synthesis of ketomethylene derivatives of the tripeptide Phe-Gly-Pro (“keto-ACE”, compound 5a) 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.
本发明涉及一种用于合成苯丙氨酸-甘氨酸-脯氨酸的酮基亚甲基衍生物(“keto-ACE”,化合物5a)及其类似物的过程。合成过程通过α,β-不饱和酮中间体进行。该过程的一个关键特征是将α,β-不饱和酮-膦酸酯与乙酰乙酸乙酯进行Horner-Emmons烯烃化反应。本发明所述的通过该过程产生的Keto-ACE类似物显示出C-域选择性。
