Abstract

An green and convenient approach to the synthesis of 3,6,9-aryl-1,8-dioxo-1,2,3,4,5,6,7,8-octahydroxanthene derivatives from appropriate aromatic aldehydes and 5-aryl-1,3-cyclo-hexanedione in the presence of two drops of concentrated H2SO4 as a catalyst in water is described. This method provides several advantages such as environmental friendliness, low cost, excellent yields, and simple workup procedure.
