실험 절차
132 ml (826 mmol) of HSiEt3 were added to 86 g (413 mmol) of β-hydroxy ester f1 in 800 ml of CH2Cl2. 102 ml (826 mmol) of BF3 -ether were added in portions at -5°--10° C. in the course of 5-10 minutes. After 20 hours at room temperature, the mixture was worked up. After hydrolysis with 220 ml of NaHCO3 (pH 3), the mixture was extracted with ether, and the organic phase was separated off, washed with NaCl solution, dried and distilled (120° C./1 mmHg).
