The Hantzsch-type microwave-assisted, solvent-free sequential three-component reaction between primary amines, β-dicarbonyl compounds and α-bromoesters in the presence of indium trichloride afforded 2-pyrrolin-5-ones, which are difficult to access by alternative methods. Ready access to these compounds allowed their use as synthetic building blocks in a target-oriented project aimed at the synthesis of a compound that had previously been postulated as a candidate for HIV integrase inhibition on the basis of computational studies. The versatility of 2-pyrrolin-5-ones was further verified by their use in a diversity-oriented synthesis context, leading to a library of highly functionalized bispiro compounds. The overall process leading to these compounds involved the generation of six bonds and two cycles over three steps, two of which are multicomponent, and the fully controlled generation of up to four stereocenters, including two quaternary ones.
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.
