A series of novel 10-amino-9-aryl-2,3,4,5,6,7,9,10-octahydroacridine-1,8- dione derivatives 4 were synthesized by hydrazine or phenylhydrazine and 9-aryl-1,8-dioxo-2,3,4,5,6,7,9-heptahydroxanthene derivatives 3, which were prepared by 5-substituted-1,3-cyclohexanedione 1 and aromatic aldehydes 2 in the presence of concentrated H2SO4 as a catalyst in water. The structures of all compounds were characterized by IR, MS, 1H-NMR, and elemental analysis, and the title compounds possess good fluorescence properties..

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. Copyright
