The Schiff's bases 3a-3h were synthesized by reacting substituted/unsubstituted aromatic aldehydes 2a-2h with 1-(2-aminoethyl)-piperazine 1. A series of novel aryl-3-(2-piperazin-1-ylethyl)-1,3-thiazolidin-4-one 4a-4h and 3-chloro-1-2-[4-(chloroacetyl)piperazin-1-yl]ethyl}-4-arylazetidin-2-one 5a-5h were synthesized from the Schiff's bases of 1-(2-aminoethyl)-piperazine 3a-3h. The structures of synthesized compounds were confirmed by analytical (C, H, and N) and spectral (FT-IR, H-1 NMR, C-13 NMR, and Mass) data. The compounds 4a-4h and 5a-5h were screened for antimicrobial activity. The compounds 4a, 4d, 4f, 4g, 5a, 5d, 5f, and 5g exhibited substantially significant antibacterial as well as antifungal activity.
