[ 1 ] - 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

[ 2 ] - Clean synthesis of 1,8-dioxo-octahydroxanthene derivatives using NBS as an efficient and almost neutral catalyst in aqueous media

An efficient one-pot condensation for the synthesis of 1,8-dioxo-octahydroxanthene is achieved through a condensation of aryl aldehydes and 5,5-dimethyl-1,3-cyclohexandione in the presence of NBS. This method enjoys several advantages such as low cost, simple work up procedure and safe reaction condition. In addition, water was chosen as a green solvent.
