Abstract
Process for obtaining benzheterocyclic compounds with the ring skeleton of formula, ** (see formula) ** Wherein x means an oxygen atom or a sulfur atom, which in the 3-position contain a free or functionally modified carboxyl radical or an acyl radical and in the 4-position an oxo, has or imino radical, or its oxides, as well as the salts of such compounds, characterized in that a) the ring of a benzheterocyclic compound is closed with the ring system of formula v, ** (see formula) ** Wherein the 2-position is substituted by an ethenylamino radical, which carbon atom contains as substituent a functionally modified carboxyl radical, reaction layers and a functionally modified carboxyl radical or an acyl radical, or a tautomer thereof, or b) closes the ring of a compound with the ring system of formula vi, ** (see formula) ** Wherein, at least, one of the ortho positions of the carbocyclic ring is unsubstituted and that at the 5-position of the heterocyclic ring contains a free or functionally modified carboxyl radical or an acyl radical, and in the 6-position an oxo, thiono radical or imino, and, if desired, in a compound obtained substituents are introduced and/or in a obtained compound the existing substituents are dissociated or transformed, and, or, if desired, a free compound obtained is transformed into its salts or a salt obtained in the free compound or in another salt.
