실험 절차
To a solution of epoxide 30 (3.0 g, 0.0098 mol) in dichloromethane (30.0 ml) was added cyclopropyl methanol (60.0 ml) at ambient condition and stirred for 5 minutes. To the above solution was added boron trifluoride-ethyl ether complex (3.0 ml, 0.0238 mol) slowly at such a rate so as to maintain the temperature of reaction between 25° C. to 30° C. The reaction was stirred at ambient temperature for 18 hours. A saturated aqueous solution of sodium carbonate (3.0 g) was added carefully and the resulting mixture was extracted with dichloromethane (30 ml). The organic phase was separated followed by usual workup and FC to give ether-alcohol 44 (1.5 g, 40.5%).
