Microwave assisted Synthesis and Antimicrobial Activity of Substituted Pyrrolidinone derivatives

A microwave assisted green synthetic methodoloy was developed for the synthesis various substituted pyrrolidinones derivatives by the one-pot three component reaction of aromatic aldehydes, aniline with dialkylbut-2-ynedioate in the presence of p-TsOH in water medium. The compounds were screened for their in vitro antimicrobial activity against four bacterial organism and two fungal organisms, resulted moderate to good activity with compared to their standard drug.
