実験手順
In the same apparatus as in Example 1, 3-acetoxy-2-allyl-3-methyl-4-cyclopentenone (19.4 g), propionic acid (70 ml) and sodium propionate (5 g) were charged and agitated at 110° to 120° C. for 6 hours. After the completion of the reaction, propionic acid was evaporated off under reduced pressure. The residue was extracted with toluene (70 ml) and water (40 ml) and treated as in Example 1 to obtain 2-allyl-4-propionyloxy-3-methyl-2-cyclopentenone (16.1 g). Yield, 83%. B.P., 115°-120° C./0.1-0.2 mmHg.
