A novel route for tandem C–C/C–N formation, annulation and aromatization of hydrazones with 1,2-dichloroethane to synthesize 1H-pyrazoles has been developed. Furthermore, the 1,2-dichloroethane serves as alkylation reagent in good to excellent yields. This methodology features mild reaction conditions and good functional group tolerance, providing a direct approach for the preparation of 1H-pyrazoles.

A series of fluorophenylpyrazole-picolinamide derivatives were synthesized in high yields using a cross-coupling reaction catalyzed by in situ formed palladium-N-heterocyclic carbenes (Pd-NHCs). The synthesized novel derivatives were evaluated for in vitro anticancer activity against a panel of four human tumor cell lines, HeLa (cervical), A-549 (lung), MCF-7 (breast), and IMR-32 (neuroblastoma). Four compounds, 11c, 11e, 11j, and 11k, showed growth inhibition (low μM) comparable with the standard drug cisplatin, providing a preliminary structure–activity relationship for the series. The present procedure is operationally simple and works with a wide range of substrates and may thus be useful in further compound optimization.

Successive treatment of arenes with β-bromopropionyl chloride and AlCl3, followed by the reactions with hydrazines and Na2CO3, and then with MnO2 gave the corresponding 3-arylpyrazoles in one pot in good to moderate yields. The same successive treatment of arenes with β-bromopropionyl chloride and AlCl3, followed by the reactions with hydroxylamine and KF gave the corresponding 3-arylisoxazolines in one pot in good to moderate yields.
