GREEN CHEMISTRY: ONE-POT THREECOMPONENT PAAL-KNORR SYNTHESIS OF NEW PYROLLE DERIVATIVES UNDER MICROWAVE IRRADIATION

4-Hydroxy pyrrole derivatives were synthesized via three-component paal-knorr reaction of β-dicarbonyl compounds and arylglyoxals in good yields using water as solvent and MW irradiation. Ammonium acetate used as the source of amine. Various derivatives of pyrroles synthesized and characterized by IR and NMR spectroscopies.
