5-对硝基苯基糠醛 | 5-(4-nitrophenyl)-2-furaldehyde | 7147-77-5 | C11H7NO4 | 217.181 |
A novel series of N-acetyl-3-aryl-5-(5-(p/o-nitrophenyl)-2-arylfuryl/thienyl) substituted pyrazoline (3a-o) were synthesized by the reaction of 1-aryl-3-(5-(p/o-nitrophenyl)-2-furyl/thienyl)-2-propene-1-one with hydrazine hydrate in acetic acid medium. The structures of the newly synthesized compounds were established by IR, 1H NMR, mass spectra and single crystal X-ray study. The synthesized compounds were subjected to antioxidant activity using DPPH scavenging assay. The compounds 3a, 3f, 3h and 3o showed moderate activity.
