실험 절차

An ozone gas was blown into a solution (200 mL) of propyl 3-methylidenecyclobutanecarboxylate (15 g) in methanol at −78° C. for 2 hr. Dimethyl sulfide (21 g) was added to the reaction mixture at the same temperature, and the mixture was warmed to room temperature over 1 hr. The obtained mixture was concentrated and purified by silica gel column chromatography to give the title compound as a colorless oil (13 g, 88%).
