Synthesis of pyrazoline derivatives from the 1,3-dipolar cycloadditions using α,β-unsaturated cyclohexanone derivatives Ziani, Nouara Lamara, Kaddour Sid, Assia Willem, Quentin Dassonneville, Benjamin Demonceau, Albert Acetic acid Pyrazolines Spectroscopy Hydrazine hydrate 1 3-Dipolar cycloadditions α β-Unsaturated cyclohexanone derivatives A series of 2-pyrazolines (3a-d) were obtained by reaction 1,3-dipolar cycloadditions of α,β-unsaturated cyclohexanone derivatives (2a-c) with hydrazine hydrate and 4-nitrophenylhydrazine in the presence of acetic acid and ethanol as solvents. The structures of the synthesized compounds were confirmed by spectroscopic methods; IR, 1H and 13C NMR.
