A novel one-pot synthesis of some new interesting pyrrole derivatives

11-(1H-Pyrrol-1-yl)-11H-indenol[1,2-b]quinoxaline and 3-(1H-pyrrol-1-yl)indolin-2-one derivatives are synthesized in good yields in a novel, one-pot, and efficient process by condensation of 11H-indenol[1,2-b]quinoxalin-11-one or isatin derivatives with 4-hydroxyproline on solid-support montmorillonite K10 under microwave irradiation.
