Catalytic Synthesis of 1,2-Azole and Pyridine Derivatives of 1,8-Dioxooctahydroxanthenes Using FIBAN K-1 Fibrous Sulfonic Cation Exchanger

Arylmethylenebis(3-hydroxy-2-cyclohexen-1-ones) were obtained by condensation of 1,2-azole- and pyridine-substituted aromatic aldehydes of the vanillin series with 1,3-cyclohexanedione in methanol in the presence of trimethylamine. Catalytic cyclization using fibrous sulfocationite FIBAN K-1 gave corresponding 1,8-dioxooctahydroxanthenes.
