Description
A simple and efficient method has been developed for the synthesis of various 2-quinoxalinone-3-hydra-zone derivatives using microwave irradiation technique. The series of 2-quinoxalinone-3-hydrazonederivatives synthesized, were structurally confirmed by analytical and spectral data and evaluated fortheir antimicrobial activities. The results showed that this skeletal framework exhibited marked potencyas antimicrobial agents. The most active antibacterial agent was 3-{2-[1-(6-chloro-2-oxo-2H-chromen-3-yl)ethylidene]hydrazinyl}quinoxalin-2(1H)-one,7while 3-[2-(propan-2-ylidene)hydrazinyl]quinoxalin-2(1H)-one,2appeared to be the most active antifungal agent
