MCM-41 functionalized sulfonic acid catalyzed one-pot synthesis of 1,8- dioxo-octahydroxanthenes
MCM-41-R-SO3H catalyzed one-pot synthesis of 1,8-dioxo-octahydroxanthenes is reportedunder reflux conditions. The catalyst is easily prepared, highly stable, very simple to handle andrecycled for five times without loss of significant activity
متن کاملBoric acid as a highly efficient and reusable catalyst for the one-pot synthesis of 1,8-dioxo-octahydroxanthenes under solvent-free conditions
An efficient and simple procedure for the synthesis of 1,8-dioxo-octahydroxanthenes from the aromatic aldehydes and 5,5-dimethylcyclohexane-1,3-dione (dimedone) in the presence of boric acid [BO3H3 or B(OH)3] as an inexpensive and reusable catalyst is described. The salient features of this methodology are: the elimination of corrosive liquid acids, high yields, simple methodology, short reacti...
