実験手順

To a solution of 5.75 g of tetrahydro-3-(3-methylenepentyl)-2H-pyran-3-ol in 40 ml methylene chloride was added in four portions, 6.5 g of 40% peracetic acid in acetic acid containing 145 mg of anhydrous sodium acetate. A temperature increase from 20° C. to 37° C. resulted. The resulting solution was refluxed for 1 hour and stirred at ambient temperature for 4 hours. The resulting mixture was diluted with 60 ml of methylene chloride and washed with 100 ml of water. The organic phase was washed successively with two 100 ml portions of 25% potassium carbonate, and 100 ml of saturated sodium chloride, dried with MgSO4 and vacuum concentrated to leave 5.7 g of the desired product as an oil.
