N-methylhydrazones with the obtained nitroalkenes gave the corresponding pyrazoles. Among the prepared pyrazoles, derivative 6j, which contains a catechol moiety, showed simultaneously a potent 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity and an α-glucosidase inhibitory activities.
