実験手順
To a stirred solution of 3.22 g of 3-chloroperbenzoic acid dissolved in 20 ml of methylene chloride under nitrogen, was added dropwise 3.05 g of tetrahydro-6-(3-methylenepentyl)-1,4-dioxepin-6-ol while maintaining the temperature below 30° C. using a water bath. After six hours and 20 minutes, the reaction mixture was washed with a 25% solution of potassium carbonate and a saturated sodium chloride solution, dried and stripped to yield 2.10 g of the desired product as a dark brown liquid.
