Rezumat:

Azulenic β-diketones were synthesized in the reaction of different β-diketones with 1-azulenecarboxylic acid chloride, in the presence of MgCl2 and pyridine, as a result of condensation and subsequent acyl elimination. The obtained dicarbonyl compounds were used for the generation of azulenic pyrazoles and isoxazoles. The structure and some physico-chemical properties of the obtained products were reported.
