In this ongoing research, our objective is to synthesize Oxazines and Thiazines by employing Chalcones, providing an uncomplicated approach for generating diverse heterocyclic derivatives. These substances show a wide spectrum of biological impact, i.e. analgesic, anti-phlogistic, and anti-convulsant properties. To characterize these newly synthesized compounds, we conducted comprehensive analyses employing techniques such as infrared spectroscopy (IR), proton nuclear magnetic resonance (1H NMR), carbon-13 nuclear magnetic resonance (13C NMR), and mass spectrometry. Additionally, we evaluated the antimicrobial potential of these compounds.
