An efficient, simple and one-pot protocol for synthesis of 1,8-Dioxo-octahydroxanthene derivatives via multi-component reactions between dimedone and various aromatic aldehydes employing barium perchlorate as catalyst is described.  The structural features of the synthesized compounds were characterized by IR and ¹H NMR. The presented method is available, environmentally friendly, cheap and highly effective to give the products in good to excellent yields.
