1-Ethoxycarbonyl-3-phenylpropyl]-L-alanine (ECPP A)

ECPP-A is the key chiral side-chain intermediate shared by the ACE-inhibitor antihypertensives Enalapril and Ramipril, supplying the ethyl-ester-protected phenylpropyl-alanine fragment that is coupled to each API’s respective bicyclic amino-acid core.
