Zusammenfassung: | The present invention is directed to phenylalkylthienylalkanoic acids and related compounds having a mercaptoalkanoic acid substituent. These compounds are useful in the treatment of bronchial asthma and they are obtained by the reaction of an appropriate epoxy compound with a mercapto alkanoic acid. Both reactants in this process are used as the ester so that the reaction gives a diester which is then hydrolyzed to the corresponding free acids by standard procedures. |
