Reaction Steps

To a solution of 7-benzyloxymethyl-7-methyl-1,4-dioxaspiro[4.5]decane (5.3 g, 19 mmol) in a mixed solvent of acetone (42 ml) and water (11 ml) was added pyridinium p-toluenesulfonate (4.8 g, 19 mmol), and the mixture was stirred with heating at 80° C. for 2 hr. After cooling, to the reaction mixture were added ethyl acetate and water, and the organic layer was separated. The aqueous layer was extracted with ethyl acetate, and the combined organic layers were washed successively with water and saturated brine, and dried over sodium sulfate. Sodium sulfate was removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel chromatography to give the title compound (3.9 g, yield 88%).
