Reaction Steps
Pyridinium p-toluene sulfonate (68.2 mg, 271 μmol) was added to a methanol (1.22 ml) solution of (2S,3aS,4E,6S,7S,11R,13aR)-11-{[tert-butyl(dimethyl)silyl]oxy}-6,13a-dimethyl-7-[(1E)-1-methylbuta-1,3-dien-1-yl]-2-phenyl-3a,6,7,10,11,12,13,13a-octahydro-9H-[1,3]dioxolo[4,5-f]oxacyclododecin-9-one (36.0 mg, 0.07 mmol) and the reaction solution was stirred at room temperature for four days. Distilled water (1 ml) was added to the reaction solution, and the reaction solution was diluted with ethyl acetate and washed with distilled water and brine sequentially, and after dried over anhydrous sodium sulfate, the drying agent was filtered off and the organic layer was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (Merck, commercial name Silica Gel 60, 230-400 mesh; hexane:diethyl ether=1:3) to obtain the title compound (18.3 mg) as a white solid.
