Procedure

10 Grams of 3-acetyl-6,10,14-trimethyl-5,9,13-pentadecatriene-2-on (Compound No. 2 in the Table) were dissolved in 10 g of dioxane, and one gram of 5% palladium-carbon was added to the solution. The mixture was catalytically reduced in hydrogen flow at an ordinary temperature under atmospheric pressure. After the reaction was completed, the palladium-carbon was filtered off, and the filtrate was subjected to distillation under the reduced pressure, to obtain 10 g of oily product. The product was purified by the column chromatography method as described in Example 1.
