실험 절차

DAST (0.16 gram, 1 mmol) was added slowly to a cooled solution (−78° C.) of Compound 29a (0.047 gram, 0.1 mmol) in dichloromethane (2 ml) and the resulting mixture was allowed to warm to room temperature and was thereafter stirred for 12 hours. The reaction mixture was then poured to a saturated solution of sodium bicarbonate), diluted with water, extracted thrice with dichloromethane, washed with brine, and dried over sodium sulfate. Removal of the solvent under reduced pressure afforded Compound 35a (0.036 gram, 78% yield) having a purity of 94%, as determined by HPLC. The compound was used in the following procedures without further purification.
