There are disclosed compounds of the formula
in which R1 is an alkenyl or alkynyl group optionally substituted with an optionally substituted phenyl group and containing from 5 to 30 carbon atoms, and R3, R4 and R5 are each selected from hydrogen, carboxyl, C2.5 alkoxycarbonyl, C1-4 alkyl, C1-4 alkoxy, hydroxyl, optionally protected tetrazolyl, halo, trifluoromethyl, nitrile, nitro and -CONR210 where each R10 is hydrogen or C1-4 alkyl.
The compounds are intermediates useful for preparing pharmaceutical compounds of the formula
in which R1, R3, R4 and R5 have the values given above and R2 is optionally substituted phenyl or optionally substituted C1-10 alkyl.
