Tetrabutylammonium Fluoride → HCID 21024022, compound

Participants

Reaction Steps

A 1.0M solution of tetrabutylammonium fluoride (0.026 mmol) in tetrahydrofuran (0.026 mL, 0.026 mmol) was added to a solution of (8E,12E,14E)-7-acetoxy-3-t-butyldimethylsiloxy-6,21-bis(1-ethoxyethoxy)-6,10,12,16,20-pentamethyl-18,19-epoxytricosa-8,12,14-trien-11-olide (19 mg, 0.024 mmol) in tetrahydrofuran (0.5 mL) at room temperature. The mixture was stirred at room temperature for 2 hours. Further, 0.026 mL of a 1.0M solution of tetrabutylammonium fluoride in tetrahydrofuran (0.026 mL, 0.026 mmol) was added thereto at room temperature. After the reaction mixture was diluted with ethyl acetate, it was 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=70:30) to obtain the title compound (112 mg, 63%) as a colorless oil.
