Silica Sulfuric Acid-Catalyzed Reaction of 4-Hydroxy Proline with 11H-Indeno[1,2-b]quinoxalin-11-one and Isatin Derivatives: A Novel Synthesis of New Pyrrole Compounds

Abstract

Facile reaction involving 4-hydroxy proline and activated carbonyl compounds such as 11H-indeno[1,2-b]quinoxalin-11-one and isatin derivatives catalyzed by silica sulfuric acid under microwave irradiation yielding some novel 11-(1H-pyrrol-1-yl)-11H-indeno[1,2-b]quinoxaline and 3-(1H-pyrrol-1-yl)indolin-2-one derivatives are described.

Key words

proline derivatives - carbonyl derivatives - silica sulfuric acid - microwave irradiation
