| Abstract: | A convenient and efficient method is described for the synthesis of alkoxy substituted 2H-chromens by l-proline catalyzed reaction of salicylaldehydes with diketone in alcohol. The method is applicable for various substituted salicylaldehydes and aliphatic as well as benzylic alcohols. |
| Keywords: | Salicylaldehyde Pentane-2 4-Dione 2H-Chromens l-Proline |
