실험 절차

p-Toluenesulfonic acid monohydrate (0.16 g, 0.84 mmol) was added to a stirred solution of (6Z,8aR,9R,10R,11aS)-4,5,8,8a,9,10,11,11a-octahydro-9-((S,E)-5-phenyl-3-(tetrahydro-2H-pyran-2-yloxy)pent-1-enyl)-10-(tetrahydro-2H-pyran-2-yloxy)cyclopenta[b]oxecin-2(3H)-one (9.0 g, 16.7 mmol) in methanol (90 mL). The mixture was stirred for 2 hr at room temperature (TLC monitoring). Then, the reaction mixture was washed with saturated aqueous solution of sodium bicarbonate (100 mL). The organic layer was separated and the water layer was extracted with ethyl acetate (100 mL). The combined organic layers were dried over magnesium sulfate, filtered and concentrated under reduced pressure to give 9.0 g of crude product. The crude product was purified by column chromatography providing 3.5 g of the title compound (56.5% yield).
