Ethyl vinyl ether → HCID 21024015, compound

Participants

Reaction Steps

Ethyl vinyl ether (82 mg, 1.1 mmol) and pyridinium p-toluenesulfonate (9.2 mg, 0.036 mmol) were added to a solution of 7-acetoxy-3-t-butyldimethylsiloxy-21-ethoxyacetoxy-6-hydroxy-6,10,12,16,20-pentamethyl-18,19-epoxytricosa-8,12,14-trien-11-olide (27 mg, 0.036 mmol) in dichloromethane (1.5 mL) at room temperature. The mixture was stirred at room temperature for 17 hours. The reaction solution was diluted with ethyl acetate, washed with brine, dried over anhydrous magnesium sulfate and evaporated. The resulting crude product was purified by silica gel column chromatography (Kanto silica gel 60N, spherical, neutral, 40 to 100 μm, eluate; hexane:ethyl acetate=80:20) to obtain the title compound (16 mg, 54%) as a colorless oil.
