Reactions of 1,6-disubstituted 3,4-dihydroxy-2,4-hexadiene-1,6-diones with hydrazine hydrate or hydrochloride afforded heterocyclization products, 3,3′-bipyrazoles. The chemoselective reaction of 1,6-diaryl-3,4-dihydroxy-2,4-hexadiene-1,6-diones with arylhydrazines gave rise to 1,1′,5,5′-tetraaryl-3,3′-bipyrazoles and 1 ,5-diaryl-3-aroylacetylpyrazoles. The specific structural features of the pyrazole derivatives obtained are discussed. Some pyrazoles show bacteriostatic and antileukemic activity.
