実験手順
To a stirred solution of the C40 diol compound (O) (0.12 g, 0.13 mmol) in CH2Cl2 (5 mL) at 0° C. were added ethyl vinyl ether (0.71 mL, 0.73 mmol) and pyridinium p-toluenesulfonate (10 mg, 0.05 mmol). The mixture was stirred at room temperature for 20 h. The mixture was then diluted with CH2Cl2 (20 mL), washed with saturated NaHCO3 (10 mL×3), dried over anhydrous K2CO3, filtered, and concentrated under reduced pressure. The crude product was purified by silica gel (deactivated by Et3N) column chromatography to give the bis(1-ethoxyethyl)ether (P-3) (0.13 g, 0.12 mmol) in 90% yield.
