Reaction Steps

The same procedure as that described in Example 25 was repeated except that 0.73 g of metallic magnesium, 80 ml of tetrahydrofuran, three droplets of ethylene dibromide, 7.4 g (0.03 mol) of geranyl chloride having a purity of 70%, 4.1 g (0.03 mol) of anhydrous zinc chloride, 0.2 g of CuI, 3 g (0.02 mol) of 3-chloromethylheptenone and 30 ml of tetrahydrofuran were used. Thus, 4.1 g of the objective compound was obtained as a colorless liquid (yield: 78.2%, purity: 98.8%).
