Abstract :
An efficient method for the synthesis of mono and bulky 1,8-dioxooctahydroxanthenes was
developed by the reaction of dimedone or 1,3-cyclohexadione and aldehydes or some bisaldehydes
in the presence of polyvinylpolypyrrolidone supported oxalic acid (PVPP-OXA) as a new
polymeric catalyst in ethanol at room temperature. Polyvinylpolypyrrolidone supported oxalic acid
was characterized by FT-IR, and TGA analysis. Clean methodologies, simple preparation of the
catalyst, high yields, environment-friendly and reusable catalyst are some advantages of this work.
