Abstract: | Aryl‐furyl substituted pyrazolines 2a–c and 4a–c were prepared by the reaction of α,β‐unsaturated carbonyl compounds with hydrazine or phenyl hydrazine. N‐chloroacetyl derivatives 3a–c were obtained by the N‐acetylation of 2a–c . The antibacterial activities of synthesized pyrazolines were examined by employing the disk‐diffusion technique. All synthesized compounds showed antibacterial effects in 1200 μg concentration. © 2003 Wiley Periodicals, Inc.
