A process for the production of amides of N-[1-(S)-(ethoxycarbonyl)-3-phenylpropyl]-L-alanine is described. The process can be used for the production of key intermediates and finally the ACE inhibitors such as Ramipril, Enalapril, Quinapril, Trandolapril, Delapril and Moexipril starting from N-[1-(S)-(ethoxycarbonyl)-3-phenylpropyl]-L-alanine by the reaction with the appropriate amines.

The synthesis and angiotensinconvertingenzyme (ACE) inhibiting activities of quinapril (CI-906, 22), its active diacid (CI-928, 33), and its dimethoxy analogue (CI-925, 25) are reported. These tetrahydro-3-isoquinolinecarboxylic acid derivatives possess equivalent in vitro potency and in vivo efficacy to enalapril. Sulfhydryl analogues with the same structural variation are also highly potent. In

angiotensin converting enzyme (ACE) inhibitors is described. An optimization effort guided by in situ IR analysis resulted in a general amide coupling approach facilitated by N-carboxyanhydride (NCA) activation that was further characterized by reaction kinetics analysis in batch. The three-step continuous process was demonstrated by synthesizing 8 different ACE inhibitors in up to 88 % yield with throughputs

synthesis of ramipril 1 utilizing (i) an environmentally benign process for the esterification of racemic 2‐aza‐bicyclo‐[3.3.0]‐octane‐3‐carboxylic acid hydrochloride 2 using boric acid as a catalyst and (ii) a robust resolution process for the synthesis of 3a by means of inexpensive and recyclable L‐(+)‐mandelic acid as key steps.
The synthesis of the title compound 8c is described. The inhibitor of AngiotensinConvertingEnzyme (ACE) contains aza-2 bicyclo [2, 2, 2] octane-carboxylic acid, a bulky cyclic amino acid replacing the proline moiety present in most ACE inhibitors described in the literature. Structural analysis of 8c supports the hypothesis of preferred conformations for this type of pseudo peptidic molecule, in
描述了标题化合物8c的合成。血管紧张素转化酶(ACE)的抑制剂包含aza-2双环[2,2,2]辛烷羧酸,这是一种取代文献中描述的大多数ACE抑制剂中脯氨酸部分的庞大环状氨基酸。8c的结构分析支持这种假肽分子在溶液(1 H,13 C NMR)和固态(X射线)中优选构象的假设。
