Procedure
8-Cyclopropyl-1,4-dioxaspiro[4.5]decan-8-ol (1.8 g) was dissolved in acetone (30 mL). A solution of water (15 mL) and conc. HCl was added. The reaction mixture was stirred overnight. The reaction mixture was taken in ethyl acetate and washed with sat. NaHCO3. Purification by silica chromatography produced 4-cyclopropyl-4-hydroxycyclohexanone (0.5 g, 27%). 1H NMR (400 MHz, CDCl3): δ 2.80-2.69 (m, 2H), 2.50-2.42 (m, 2H), 1.99-1.78 (m, 4H), 1.01-0.99 (m, 1H), 0.50-0.47 (m, 4H); MS (ESI) m/z: Calculated for C9H14O2: 154.1. found: 155.1 (M+H)+.
