Reaction Steps

A mixture of 31 g of diethyl heptylidenepropanedioate (B. Wojcik and H. Adkins, J. Am. Chem. Soc., 56, 2424 (1934), prepared by the method of A. C. Cope and K. E. Hoyle, J. Am. Chem. Soc., 63, 733 (1941)), 5 g of potassium bicarbonate and 17 g of 30% hydrogen peroxide in 200 ml of methanol was stirred for two hours at 40° C., then allowed to stand at 20° C. for 16 hours. The mixture then was concentrated to 50 ml; 100 ml of water was added and the solution was extracted with two 50-ml volumes of methylene chloride. The solvent was evaporated to give a colorless liquid, which was vacuum distilled to give diethyl 3-hexyloxiranedicarboxylate (2A), bp: 117°-126° C. at 0.1 Torr.
