Regioselectivity of the Synthesis of 2-Pyrazolinylthiazoles by reacting 2-Hydrazinothiazoles with Unsymmetrical β-Diketones

Regioselectivity of the Synthesis of 2-Pyrazolinylthiazoles by reacting 2-Hydrazinothiazoles with Unsymmetrical β-Diketones

Novel 2-pyrazolinylthiazoles 1 are prepared by reaction of 2-hydrazinothiazoles 2 with 1,3-dicarbonyl compounds of type 3. The conditions of the aromatization of 1 to 2-(3-aryl-5-trifluoromethylpyrazol-l-yl)thiazoles 4 have been investigated.
