چکیده
|
An efficient method for the synthesis of mono and bulky 1,8-dioxooctahydroxanthenes wasdeveloped by the reaction of dimedone or 1,3-cyclohexadione and aldehydes or some bisaldehydesin the presence of polyvinylpolypyrrolidone supported oxalic acid (pvpp-oxa) as a newpolymeric catalyst in ethanol at room temperature. polyvinylpolypyrrolidone supported oxalic acidwas characterized by ft-ir, and tga analysis. clean methodologies, simple preparation of thecatalyst, high yields, environment-friendly and reusable catalyst are some advantages of this work.
