There are disclosed substituted phosphonamides and related compounds of the general formula
wherein:
R, is alkyl or substituted alkyl of C1-C6 wherein the substituent is halo, amino, acylamino; aralkyl wherein the alkyl is C1-C4 optionally substituted by amino or acylamino and wherein the aryl function is phenyl or naphthyl optionally substituted by halo or hydroxyl; or, heteroaralkyl wherein the alkyl is C1-C4 optionally substituted by amino or acylamino and wherein the heteroaryl group can be indolyl or thienyl;
R2 is H, lower alkyl of C1-C4, aralkyl.
R3 is lower alkyl of C1-C6 optionally substituted by an amino group;
R4 is H, lower alkyl of C1-C6, aralkyl.
X is (CH2)n wherein n is 1 or 2, CH-OCH3, CH-OH, or S; and,
the pharmaceutically acceptable salts thereof. THese compounds are useful as converting enzyme inhibitors and as antihypertensives.
