Synthesis and Antimicrobial Activity of 4-(4-Acetylphenyl)-3-Hydroxy-2H-Chromen-2-One Derivatives

Reactions of 4-(4-bromoacetylphenyl)-3-hydroxy-2H-chromen-2-one with Py, 4-methylpyridine, quinoline, and benzo[f]quinoline produced quaternary salts; with dinucleophiles, derivatives of thiazole, imidazo[1,2-a]pyridine, and imidazo[1,2-a]pyrimidine. Several of the target compounds exhibited high antimicrobial activity that indicated further research on these compounds is warranted.
