Reaction Steps
A solution of 7,9-dimethyl-2-oxaspiro[5.5]undec-8-en-1-ol (5.0 g, 26 mmol) and p-TsOH (50 mg) in methanol (20 ml) was stirred at reflux temperature for 0.5 hours. The mixture was diluted with MTBE, washed with water and brine, dried (MgSO4) and concentrated in vacuo. The residue was distilled bulb-to-bulb to yield a colorless oil (4.3 g, 80%).
