Sulfated zirconia results to be a very efficient catalyst for the synthesis of 1,8-dioxo-octahydroxanthenes and 1,8-dioxo-decahydroacridines without tedious work-up procedures. While 1,8-dioxo-octahydroxanthenes are prepared from aldehyde and 5,5-dimethyl-1,3-cyclohexenedione (dimedone), 1,8-dioxo-decahydroacridines are prepared from this reactant mixture with amines. This method provides a mild catalytic
