実験手順

Methyl 2-methyl-2-(8-nonenyloxy)propionate (40 g) was dissolved in 320 ml of methylene chloride, and 40.8 g of 70% 3-chloroperbenzoic acid was added with stirring under ice-cooling, and the mixture was stirred for 15 hours at room temperature. The reaction solution was filtrated to remove insolubles, and the filtrate was concentrated. The residue was dissolved in n-hexane and washed 4 times with aqueous 10% potassium carbonate solution, washed with water, dried over anhydrous magnesium sulfate and concentrated to give 43.2 g of the objective compound as colorless oil.
