| Abstrakt: | A novel, efficient and one-pot method for preparation of 1, 8-dioxo-octahydroxanthene derivatives is reported using Nafion-H as an effective heterogeneous catalyst under thermal and solvent-free conditions. This method has the advantages of high yields, a cleaner reaction, simple methodology, easy work-up and greener conditions. The catalyst is easily prepared, stable, reusable and efficient under the reaction conditions. |
