PdCl2-catalyzed heterocyclotrimerization in MeOH/scCO2:A versatile approach to dimethyl pyridine-3,5-dicarboxylate from methyl acrylate and urea
【摘要】 A novel and green method for the synthesis of dimethyl pyridine-3,5-dicarboxylate has been developed. It is PdCl2-catalyzed heterocyclotrimerization of methyl acrylate with urea in methanol/supercritical carbon dioxide. The target compound was obtained with a 75% isolated yield under the optimized con-ditions.
