Reaction Steps

4-Isopropenyl-3,7,11-trimethyl-6,10-dodecadien-1-yn-3-ol (0.260 g; 10-3 mole) is kept at the reflux temperature of tetrahydrofuran and protected from light, in the presence of silver nitrate (0.017 g; 10-4 mole) and potassium nitrate (0.101 g; 10-3 mole) in a mixture (6 cc) of tetrahydrofuran and water (2:1 by volume). After being heated under reflux for 15 hours, the reaction mixture is treated under the conditions described in Example 1. 6,10,14-Trimethyl-3,6,9,13-pentadecatetraen-2-one (0.120 g) is thus obtained, with the following characteristics:
