Abstract The o-, m- and p- isomers of (±)-2-[3-(hydroxybenzoyl)phenyl] propanoic acid (11, 12 and 4) have been prepared from 3-bromopropiophenone or m-propionylbenzoic acid, via 7, 8 and 2, which were submitted to Tl(III) nitrateinduced rearrangement, followed by hydrolysis of the ester and ether functions.
