Reactivity and microbiological activity of 2-methyl-3-carboethoxy-5-pyrrolinone derivatives

This work describes the synthesis of 2-methyl-3-carboethoxy-5-pyrrolinone which was then allowed to react with aromatic aldehydes, nitromethines, benzendiazonium salts, hydrazine and amines. Several of the products have shown good results in preliminary antimicrobial and antifungal tests.
