Participants

Reaction Steps

In the same apparatus as in Example 1, 3-acetoxy-2-n-pentyl-3-methyl-4-cyclopentenone (22.4 g), toluene (60 ml), acetic acid (10 ml) and sodium acetate (4 g) were charged and heated for 10 hours with agitation. After the completion of the reaction, acetic acid was evaporated off under reduced pressure. The residue was extracted with toluene (70 ml) and water (50 ml) and treated as in Example 1 to obtain 4-acetoxy-2-n-pentyl-3-methyl-2-cyclopentenone (18.6 g). Yield, 83%, B.P., 125°-135° C./0.2-0.5 mmHg.
