The reaction of aromatic aldehyde and 1,3-cyclohexanedione in aqueous media has been catalyzed byp-dodecylbenezenesulfonic acid (DBSA) or sodium dodecyl sulfate (SDS) and yields two products: 9-aryl-1, 8-dioxooctahydroxanthene derivatives and 2,2´-arylmethylenebis(3-hydroxy- 2-cyclohexene-1-one). This method provides several advantages such as good yield, simple work-up procedure and environment friendly.
