## Abstract Polyhydroquinolines have been synthesized in good to excellent yields (80โ€“90%) and short reaction times (15โ€“30 min) in the presence of aluminum phosphate [AlPO~4~] as heterogeneous catalyst at 90ยฐC; the reaction workup is simple and the catalyst aluminum phosphate [AlPO~4~] can be easil
