The present invention relates to compounds of the formula
wherein
B1 and B2 are each independently hydrogen; hydroxy; -OR2 wherein R2 is a C1-C4 alkyl or an Ar-Y group wherein Ar is aryl and Y is a hydrogen or C1-C4 alkyl; or, where B1 and B2 are attached to adjacent carbon atoms, B1 and B2 can be taken together with said adjacent carbons to form a benzene ring or methylenedioxy;
A is a bond, methylene or oxygen, sulfur or NR4 or NCORs wherein R4 is hydrogen, a Ci-C4 alkyl or an Ar-Y- group and R5 is -CF3, a C1-C10 alkyl or an Ar-Y- group;
R3 is hydrogen or -CH2OC(O)C(CH3)3;
R1 is hydrogen, C1-C4 alkyl or -CH20C(O)-C(CH3)3; and
n is an integer 1 to 3, which are useful as inhibitors of enkephalinase and ACE.
本发明涉及式如下的化合物
