Reaction Steps

In the same flask as used in Example 1, there were charged 5-methyl-α-(2-cis-pentenyl)furfuryl alcohol (I-2) (18 g) and water (720 g), and the mixture was stirred at 100° C. under a pH of 4.7-4.9. The reaction mixture was then treated in the same manner as in Example 1 to give a mixture (14.2 g) of 2-(2-cis-pentenyl)-3-hydroxy-3-methyl-4-cyclopentenone (II-2) and 2-(2-cis-pentenyl)-4-hydroxy-3-methyl-2-cyclopentenone (III-2).
