A one-pot cascade reaction catalyzed by multifunctional catalysts is an economical and efficient pathway in modern organic synthesis. Herein, mesoporous polymeric materials with both sulfonic acid and basic amine groups have been synthesized by solvothermal-copolymerization of divinylbenzene (DVB) and 4-styrenesulfonic sodium (StSO3−Na+) with subsequent nitration, reduction of nitro to amino groups and acidification of sulfonic sodium to obtain P(DVB–NH2–StSO3H). The mesoporous polymeric bifunctional catalyst showed excellent activity and selectivity for one-pot cascade deacetalization−Knoevenagel condensation with facile recovery due to the isolated locations of the sulfonic acid and amino groups.
