Abstract

Procedure for obtaining new pyrazoles and their derivatives, characterized, by which acids α -cyano- β -oxo-propionics, if appropriate in the form of their reactable acid and oxo functional derivatives, are condensed with N-monosubstituted hydrazines which at the N'-nitrogen atom carry a dissociable residue by hydrolysis, the obtained open-chain products are treated with hydrolyzing agents and at the same time or subsequently the pyrazole ring is closed and, if desired, in the obtained compounds, the free or functionally modified carboxylic group is still functionally modified.
