Resumo: Novel 1,4'-bipyrazoles were synthesized via highly regioselective cyclocondensation reactions of β-dimethylaminoenones with hydrazine monohydrate, tert-butylhydrazine hydrochloride, phenylhydrazine hydrochloride or carboxymethylhydrazine. X-ray diffraction technique was used in the elucidation of the regiochemistry of the β-dimethylaminoenaminones and of the 1,4'-bipyrazoles. 1,4'-Bipyrazolylisoxazoles were also reported.
