참여 물질

반응 단계

To a suspension of 60 mg (0.0025 mole) of sodium hydride in 7 ml of toluene was added 4.32 ml (0.025 mole) of ethyl benzoyl acetate. After several minutes a solution was obtained to which was added 2.41 ml (0.025 mole) of cyclohexenone. The reaction was stirred 36 hrs. at room temperature and then added to 25 ml 1 N hydrochloric acid--25 ml saturated sodium chloride--150 ml ether. The ether extract was dried over magnesium sulfate and evaporated to an oil. This crude oil was purified via column chromatography on 300 g of silica gel eluted with 50% ether--pentane to yield 4.8 g (67%) of the title compound as an oil.
