Reaction Steps

A 3.06 g quantity (0.0212 mol) of methyl ether of 2,5-diketohexanol-1 is added to 15 ml of dioxane containing 5% of triethylamine, and the mixture is heated at 100° C. for 2 hours. The reaction product is carefully neutralized with acetic acid and thereafter distilled at reduced pressure, giving 2-methoxy-3-methyl-cyclopentenone, the desired product, in a yield of 88%, b.p. 84°-85° C./18 mm Hg.
