Reaction Steps

To a solution obtained by dissolving 4.4 g of 4,4-dimethyl-3-(phenylsulfonyl) -cyclohexan-1-one in 45 ml of benzene, were added 1.1 nm of 1,2-ethanediol and 0.3 g of anhydrous paratoluenesulfonic acid. The resulting mixture was heated under ref lux 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 dried over magnesium sulfate. The solvent was distilled off under reduced pressure, followed by recrystallization from ethyl ether, whereby 4,4-dimethyl-1,1-(ethylenedioxy)-3-(phenylsulfonyl)-cyclohexane was obtained in the form of white crystals. Yield: 84%
