반응 단계
To a stirred solution of the C40 diol compound (L) (1.00 g, 1.00 mmol) in CH2Cl2 (10 mL) at 0° C. were added ethyl vinyl ether (0.80 mL, 8.00 mmol) and pyridinium p-toluenesulfonate (0.13 g, 0.50 mmol). The mixture was stirred at 0° C. for 1 h, and warmed to and stirred at room temperature for 14 h. The mixture was then diluted with CH2Cl2 (30 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 (M-3) (1.09 g, 0.84 mmol) in 95% yield.
