title: Brønsted Acid-Catalyzed Three-Component Reaction of Anilines, α-Oxoaldehydes, and α-Angelicalactone for the Synthesis of Complex Pyrrolidones.
abstract: A green and efficient three-component reaction of easily available anilines, α-oxoaldehydes, and α-angelicalactone was developed for the synthesis of highly functionalized pyrrolidones using dilute sulfuric acid as the catalyst. Products were obtained in good to high yields at room temperature and under solvent-free conditions. The reaction could also be performed on a multigram scale with the same efficiency.
