Abstract

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, 1 H and 13 C NMR.

Abstract

A series of new curcumin analogues were obtained by Claisen-Schmidt condensation of substituted benzaldehydes with cyclohexanone derivatives using the ratio of 1:2 of ketone to aldehyde in dilute ethanolic solution under base catalyzed (NaOH) conditions at room temperature in good yields. The structures of the synthesized compounds were confirmed by data of IR, 1 H NMR, and 13 C NMR spectra.
