Procedure
To a solution of 5.3 g of 3-(phenylsulfonyl)-cyclohexan-1-one in 60 ml of benzene, were added 0.3 ml of 1,2-ethanediol and 0.2 g of anhydrous paratoluenesulfonic acid. The reaction mixture was heated under reflux for 4 hours. After the reaction, a 2M aqueous sodium bicarbonate solution was added and the resulting mixture was extracted with ethyl acetate three times. The combined organic layers were washed with saturated saline and then, dried over magnesium sulfate. The solvent was distilled off under reduced pressure. The residue was recrystallized from ethyl ether, whereby 6.1 g of 1,1-(ethylenedioxy)-3-(phenylsulfonyl)-cyclohexane (m.p.: 93–95° C.) were obtained in the form of white crystals. Yield: 97%
