ovel N-acyl amino acid derivatives are irreversible inhibitors of angiotensin-converting enzyme and have the following general Formula 1:-
wherein:-
Z represents an electron-withdrawing group, preferably cyano or a carbonyl-terminated functional group;
X represents a group which, in combination with Z, can form a Michael acceptor after abstraction of the proton from the carbon atom adjacentto X, and preferably X is ethynyl or a fluoromethyl group;
R, represents hydrogen, alkyl or phenylalkyl; and
R2 represents an aminocarboxylic acid residue obtained by removal of a hydrogen atom from the amino group thereof.
Novel intermediates include compounds of the following general Formula 21:-
wherein A represents tert-butyl, dibenzyl or trityl, and compounds of the following general Formula 36 (being the combination of Formulae 29 and 35 herein):-
wherein X1 represents ethynyl or mono-, di- or trifluoromethyl;
R1 is a defined above;
Re represents hydroxy, alkoxy or amino; and
R10 represents hydrogen, alkyl, phenylalkyl, phenyl or p-methoxyphenyl.
