Abstract

Chalcones (IIIa-b) were treated with hydrazine hydrate in ethanol to give pyrazoline (IVa-b). Pyrazolines (IVa-b) reacted with acetic acid to form 1-acetyl pyrazoline (Va-b). Pyrazolines (IVa-b) were condensed with benzoyl chloride in pyridine medium to give 1-benzoyl pyrazoline (VIa-b). Pyrazolines (IVa-b) were reacted with acetic anhydride and a pinch of fused sodium acetate to give 1-acetyl-3-(2-acetoxy)-3-nitro-5-methyl)phenyl-5-substituted D²-pyrazoline (VIIa-b).
