A plurality of methods are disclosed for preparing compounds having the formula:
wherein
R is hydrogen, formyl, acetyl, propanoyl, butanoyl, phenylacetyl, phenylpropanoyl, benzoyl, cyclopentanecarbonyl, tert-butyloxycarbonyl, cyclopentanecarbonyl-L-lysyl, pyro-L-glutamyl-L-lysyl, L-lysyl, L-arginyl or pyro-L-glutamyl;
A is phenylalanyl, alanyl, tryptophyl, tyrosyl, glycyl isoleucyl, leucyl, histidyl, or valyl, the α-amino group thereof being in amide linkage with R;
R1 is hydrogen or methyl,
R2 is L-proline, L-3,4-dehydroproline, D,L-3,4-dehydro- proline, L-3-hydroxyproline, L-4-hydroxyproline, L-thiazo- lidine-4-carboxylic acid, or L-5-oxo-proline, the imino group thereof being in imide linkacge with the adiacent
and,
I n is 0 or 1, such that when n is O, R is methyl, and where n=1, and R1 is methyl the
moiety is in the D-configuration. These compounds are inhibitors of angiotensin converting enzyme.
