This invention relates to new compounds of the formula ##STR1## wherein A is a hydroxy, lower alkoxy, lower alkenoxy, diloweralkylamino lower alkoxy, acylamino lower alkoxy, acyloxy, lower alkoxy, aryloxy, arloweralkyloxy, amino, loweralkylamino, diloweralkylamino, aryloweralkylamino, hydroxyamino, or substituted aryloxy, or substituted arloweralkoxy wherein the substituent is methyl, halo or methoxy; R.sub.1, R.sub.2, and R.sub.3 are each hydrogen, lower alkyl, lower alkenyl, lower alkynyl, aryl, fused aryl-cycloalkyl, aralkyl, cycloalkyl, heterocyclic, substituted alkyl, alkenyl, or alkynyl groups in which the substituents are hydroxy, alkoxy, halo, amino, aminoalkyl, alkylamino, mercapto, or alkylmercapto, substituted cycloalkyl groups in which the substituents are alkyl, halo, haloalkyl, hydroxy, alkylamino, nitro or trifluoromethyl, and substituted aryl and heterocyclic groups in which the substituents are alkyl, hydroxy, alkoxy, hydroxyalkyl, halo, mercapto, alkylmercapto, mercaptoalkyl, haloalkyl, amino, alkylamino, aminoalkyl, nitro, methylenedioxy, or trifluoromethyl; X is hydrogen, alkyl, alkenyl or alkynyl of up to about 20 carbon atoms, aryl or aryl lower alkyl containing from about 7 to about 12 carbon atoms, heterocyclic or heterocyclic lower alkyl cycloalkyl or cycloalkylalkyl containing up to about 20 carbon atoms, or of the formula: ##STR2## wherein n=2, 3 or 4; n'=1, 2 or 3; and Ar is arylene or mono- or di- substituted arylene in which the substituent is halo, CF.sub.3, lower alkyl, OH, lower alkoxy, mercapto, amino or sulfanyl. These compounds are important intermediates in the syntheses of dipeptides which are useful in the treatment of hypertension and are effective as inhibitors of angiotensin converting enzymes.
