Versuchsvorschrift

In 10 ml of dried toluene was dissolved 5 mmol of (E)-2-cyclopentadecenone, and the solution was added dropwise to the above solution, followed by allowing the reaction to proceed at -78° C. to -60° C. for 15 hours. Thereafter, the same procedures as in Example 14 were followed to obtain muscone having an optical rotation of +11.8° (at 21° C., c 5.13, MeOH) and an optical purity of 100 %ee in a chemical yield of 90 mol %.
