This study reports the synthesis of new 1,3-oxazepine derivatives (S21-S30) by reacting hydrazones (Schiff bases) (S11-S20) with phthalic anhydride in dry benzene as the solvent. The hydrazones were prepared by reacting diphenyl acrylamide derivatives (S1-S10) with para-chloroaniline using ethanol as the solvent. The acrylamides were derived from para-substituted acetanilides treated with various para-benzaldehydes using ethanol as the solvent. All synthesized compounds have been characterized using UV-Visible and FT-IR spectroscopy. The structure of chemicals has been confirmed using proton and carbon nuclear magnetic resonance spectroscopy (1H-NMR and 13C-NMR). The purity of the synthesized chemicals was confirmed through Thin-Layer Chromatography (TLC). The antibacterial activity of the new compounds has been assessed against gram-positive bacteria (Streptococcus Pneumoniae and Staphylococcus Aureus) and gram-negative bacteria (Pseudomonas Aeruginosa and Escherichia Coli). The results showed significant antimicrobial activity at varying concentrations, with compounds S23, S26, and S30 exhibiting the highest effectiveness attributed to the electron-withdrawing halogens present in their structures.
