Abstract

Process for the preparation of thienothienylcarbonyl-phenylalkanoic acids of the general formula: ** (formula 01) ** in which r represents a hydrogen atom or an alkyl radical containing 1 to 4 carbon atoms and the symbol a-co- represents a radical ( thieno [2,3-b] thienyl-2) carbonyl or (thieno [3,2-b] thienyl-2) carbonyl, as well as, where they exist, their optical isomers, their metal salts and their addition salts with the bases nitrogenated, characterized in that a partial decarboxylation of a diacid of general formula is carried out: ** (formula 02) ** wherein r is defined as above and hoco-a- represents a radical (carboxy-5-thieno [2,3- b] thienyl-2) or (carboxy-5-thieno [3,2-b] thienyl-2), and then the obtained product is optionally separated into its optical isomers and these are optionally converted into addition salt with a nitrogenous base or in metallic salt.
