Abstract

This research included the preparation of new pyrazoline rings from chalcones of the 1,3-benzodiaoxolo ring with hydrazine and some of its derivatives, In the first step: new chalcones (H1-H3) were prepared from the reaction of 3,4-methylenedioxyacetophenone with (4-phenoxybenzaldehyde, 4-diethoxymethylbenzaldehyde, furfural) in the presence of base as a catalyst, in a second step: perform ring closure from the reaction of chalcones H1-H3 with each of (hydrazine hydrate, phenylhydrazine, 2-hydrazinopyridine, and 2-hydrazinobenzothiazole), in the presence of ethanol as a solvent without a catalyst to obtain several new pyrazoline rings (H4-H15), new compounds have been identified by spectroscopic methods, IR, 1H-NMR, 13C-NMR, DEPT 135.
