Abstract
A new, facile, and environment friendly synthesis of some novel pyrazolylpyrazoline derivatives has been achieved using one-pot multicomponent reaction of substituted aromatic aldehydes, 2-acetylpyrrole or 2-acetyl-1,3-thiazole, and substituted hydrazines in the presence of sodium hydroxide in ethanol at room temperature under ultrasonication. The salient features of this green protocol are one-pot reaction, short reaction time, and straightforward workup procedure. All synthesized compounds were characterized by spectroscopic techniques, and their in vitro antitubercular and antimalarial activities were evaluated. Some of the compounds tested showed good to excellent activity compared to standard drugs.
