Versuchsvorschrift

A solution of 8-cyclohexyl-8-methoxy-1,4-dioxaspiro[4.5]decane (1.15 g) and acetic acid (40 ml) in water was stirred at 100° C. for 6 hours. After cooling to room temperature, the reaction mixture was added to a mixture of sodium hydrogen carbonate solution and diethyl ether. The organic layer was taken, washed with sodium hydrogen carbonate solution and dried over magnesium sulfate. The magnesium sulfate was filtered off, and the filtrate was concentrated under reduced pressure to give 1-methoxy-1,1′-bicyclohexane-4-one (1.018 g).
