Abstract Synthesis of a series of symmetrical and unsymmetrical 1,8-dioxo-octahydroacridine benzenesulfonamide derivatives has been achieved by one-pot, multicomponent reaction of aromatic aldehydes and sulfanilamide with cyclic 1,3-dicarbonyl compounds by using p -toluenesulfonic acid as an effective, cheap, and efficient catalyst. Reaction progress was monitored by thin-layer chromatography (TLC)
