Disclosed herein are N-(3-mercapto-2-alkyl-1-oxopropyl)-2,3-dihydro-1H-indole-2-carboxylic acids and derivatives thereof which act as inhibitors of angiotensin converting enzyme and as anti-hypertensive agents. Derivatives include those in which the 3-mercapto group is substituted with phosphate derivatives or is replaced by a variously substituted amino group. The compounds of the invention (excluding disclosed intermediates) have the general formula: ##STR1## wherein: n is 1 or 0; R.sub.1 is hydrogen, lower alkyl, aryl or aralkyl; R.sub.2 is hydrogen or lower alkyl; R.sub.3 is hydrogen, lower alkyl or aroyl; R.sub.5 is hydroxy, amino, or lower alkoxy; X is hydrogen, hydroxy, lower alkyl, lower alkoxy, or halogen; Y is hydrogen, lower alkyl, or aryl; R.sub.4 is -SH, ##STR2## wherein L is O, NR.sub.7 or S (where R.sub.7 is hydrogen or lower alkyl); M is R.sub.8, OR.sub.8, SR.sub.8, or NR.sub.9 R.sub.10 (where R.sub.8 is hydrogen, lower alkyl, aryl, or aralkyl; and R.sub.9 and R.sub.10 are, independently, hydrogen, lower alkyl, or aryl); A is O, NR.sub.13 or S; R.sub.11 and R.sub.12 are, independently, hydrogen, alkyl, aralkyl or aryl; R.sub.13 is hydrogen or lower alkyl; m is 0, 1, 2, or 3; R.sub.20 is hydrogen or aryl; and R.sub.21 is hydroxy or lower alkoxy; or pharmaceutically acceptable salts thereof.
