A new acidic mesoporous catalyst (FSM-16/AEPC-SO3H) was successfully synthesized and characterized by FT-IR, TGA, XRD, SEM, TEM, EDS and BET techniques. The FSM-16/AEPC-SO3H showed excellent catalytic activity for the synthesis of 1,8-dioxo-octahydroxanthene and tetrahydrobenzo[b]pyran derivatives. The synthesized catalyst can also be recycled.
