A Facile Synthesis of Xanthene-1,8(2H)-dione Derivatives by Using Tetrapropylammonium Bromide as Catalyst

Several new derivatives of 9-aroyl-3,4,5,6,7,9-hexahydro-1H-xanthene-1,8(2H)-dione have been synthesized in yields varying from high to excellent by the condensation reaction of arylglyoxals with 1,3-diketones (cyclohexane-1,3-dione or dimedone) and TPAB
