Compounds of the formufa:
wherein
R1, which is attached to a carbon atom of ring "B", is hydrogen, halo, C,-C, alkyl, or -S(C1-C4 alkyl);
Y. which is attached to ring "A", is -CN, -COOH, -COO(C1-C4 aikyl) or -CONH2:
X is O, S. NH, N(C,-C, alkyl) or -CH=CH; and
R. which is attached to a carbon atom of ring "8", is a group of the formula:
where Z is -CH2-, -CH=CH-, -OCH2-, -CO- or -S-: and the pharmaceuticaliv. acceptable salts thereof.
The compounds in which Y is -COOH, -CCO(C1-C4 alkyl) and -CONH2 are pharmaceutical agents being selective thromboxane synthetase inhibitors. Those in which Y is -CN are useful intermediates.
