Abstract

"Process for obtaining thieno [2,3-b] [1] benzothiapyrans" of general formula I, ** (See formula) ** where R. represents a halogen, an alkoxy or an alkyl mercapto group, each having 1-4 carbon atoms, characterized in that an alkali metal salt of 2-mercapto-thiophene is condensed with an alkali metal salt of a compound of the general formula II, ** (See formula) ** where R. has the meaning indicated above and the compound that is formed, of general formula III, ** (See formula) ** by intramolecular ring closure it is transformed into a compound of general formula I.
