Heterocyclic compounds are one of the most important organic compounds, that frequently present as active pharmaceuticals products. Among them, nitrogen-containing heterocycles have attracted much interest from various researchers due to their wide range of biological activities. Considering the importance of all these characteristics and the very pronounced application, and as a continuation of our work on pyrazolines, this paper shows the synthesis of some new N-acyl pyrazolines in very good yields. These products were obtained by reacting chalcone analogues with hydrazine in the presence of boiling formic or acetic acid.

Keywords: chalcone analogues; heterocycle; pyrazolines
