A green and highly efficient method for the synthesis of 1,8-dioxooctahydroxanthenes catalyzed by melamine trisulfonic acid (MTSA) as a heterogenous and recyclable organocatalyst under solvent-free conditions is reported. This procedure provides many advantages such as easy work-up, clean conversions, short reaction times and high yields of the products.

Keywords: Aromatic aldehyde, chemoselective, heterogenous catalyst, dimedone, 1, 8-dioxooctahydroxanthenes, 1, 3-dicarbonyl compounds, melamine trisulfonic acid, organocatalyst, solvent-free, solid acid.
