A high-yielding, short, and scalable synthesis of a potent calpain 2 inhibitor (CAT811) is reported. The key step in the sequence involves an intramolecular macrocyclization of a 6-iodonorleucine residue to the side chain of tyrosine.

A method for the stereoselective generation of 7,6- and 7,5-fused bicyclic lactams of type 1 has been developed. The key step involves intramolecular N-acyliminium ioncyclization of N-acyl enamine 2 to generate the core bicyclic framework. Lactams of type 1 may be viewed as conformationally restricted mimics of alanyl proline.
Compounds of the formula ##STR1## are disclosed as possessing inhibotory activity against angiotensin converting enzyme (ACE) and neutral endopeptidase (NEP) and thus being useful as cardiovascular agents. Processes for preparing these compounds are also disclosed.
