실험 절차

Diphenyl sulfide (33 mg, 0.18 mmol) and 10% Pd-carbon (1.08 g) were added to a solution of benzyl 2-(1,4-dioxaspiro[4,5]decan-8-ylidene)acetate (5.0 g, 17.34 mmol) in methanol (50 ml) under a nitrogen gas stream, the atmosphere in the system was replaced five times with nitrogen gas, was then filled with hydrogen gas, followed by stirring under a hydrogen gas stream for 5 hr. The catalyst was removed by filtration through Celite pad and was washed with ethanol, and the filtrate was concentrated under reduced pressure to give the title compound as a yellow oil (4.1 g, yield 82%).
