The acid catalyzed ring closure of an appropriately substituted phenyl ketoester sulfide served as the initial reaction in the synthesis of several 3,4‐ and 3,6‐disubstituted benzo[ b ]thiophenes. One of these compounds, 4‐methoxybenzo[ b ]thienyl‐3‐acetic acid, showed marked plant growth enhancement.
