Reaction Steps

14.0 g (0.1 mol) of dimedone were dissolved in 200 ml of THF. 3.8 g (0.1 mol) of NaBH4 and 5 mmol of CeCl3 dissolved in 50 ml of THF were then added at -30° C. The mixture was stirred at room temperature for another 2 hours and was hydrolyzed at 0° C. by means of methanol/water. The organic phase was separated off and the solvent was removed. The residue was extracted with ethanol and unreacted dimedone was removed by crystallization. This gave 11.5 g (80%) of 5,5-dimethylcyclohexane-1,3-diol.
