実験手順

5 g (23 mmol) of ethyl 3-cyclopent-1-ylbenzoate (4a) and 100 ml of methylene chloride are introduced into a round-bottomed flask. The solution is cooled to 0° C. and 9 g (28 mmol) of meta-chloroperbenzoic acid are added in portions. The mixture is stirred for 30 minutes at 0° C. and then for 4 hours at room temperature. The mixture is filtered. The filtrate is successively washed with a saturated aqueous sodium thiosulfate solution, a saturated aqueous sodium bicarbonate solution and then with a saturated aqueous sodium chloride solution. The organic phase is dried over Na2SO4, filtered and concentrated under reduced pressure. The residue is purified by flash chromatography on silica gel (cyclohexane/ethyl acetate: 95:5). The title product is obtained in the form of a colorless oil (4.8 g).
