These compounds can be synthesized by reaction between the derivative asetofenon with benzaldehid derivatives in absolute ethanol and catalyzed by sodium hydroxide. The resulting compounds were characterized by IR and NMR spectroscopy then tested against three strains of bacteria namely Staphylococcus aereus.
