Structure 3a, a potent angiotensin-converting enzyme inhibitor, was prepared in five steps from L-(+)-alpha-amino-4-phenylbutyric acid by construction of the activated side-chain ester 16, displacement with L-pyroglutamate ester anion, and deblocking. Diastereomer separation was accomplished by chromatography at the diester stage, 17. Pharmacological assays established that 3a parallels enalapril in
