実験手順: After dissolving 29.95 g (0.17 mol) of 6-undecanol to 60 mL of pyridine, 29.98 g (0.26 mol) of methanesulfonyl chloride was added dropwise under cooling with ice and the mixture was stirred overnight. Thereafter, 35 mL of 0.5 N aqueous hydrochloric acid was added and the mixture was extracted twice with 200 mL of ethyl acetate. The organic layer was washed with 100 mL of water and a saturated aqueous solution of sodium chloride in that order and thereafter dried over anhydrous magnesium sulfate. After filtering off the magnesium sulfate, the solvent was distilled off to give 44.7 g of 6-methanesulfonyloxy-undecane. was added dropwise under cooling with ice the mixture was extracted twice with 200 mL of ethyl acetate The organic layer was washed with 100 mL of water a saturated aqueous solution of sodium chloride in that order and thereafter dried over anhydrous magnesium sulfate After filtering off the magnesium sulfate the solvent was distilled off

実験手順: To the solution of n-pentylmagnesium bromide in tetrahydrofuran synthesized in Example 2, 162 mL (2.0 mol) of ethyl formate was added dropwise in a nitrogen atmosphere and the mixture was stirred overnight at room temperature. After careful addition of water, the reaction mixture was neutralized with dilute hydrochloric acid and extracted with ethyl acetate. The organic layer was washed with a saturated aqueous solution of sodium chloride, dried over anhydrous magnesium sulfate and thereafter concentrated to give 340.8 g of 6-undecanol. extracted with ethyl acetate The organic layer was washed with a saturated aqueous solution of sodium chloride dried over anhydrous magnesium sulfate concentrated

実験手順: Sodium borohydride (0.55 g, 14.6 mmol) was added to a solution of 6-undecanone (1.66 g, 9.8 mmol) in 50 ml methanol, and the mixture was stirred at room temperature 2 hours. Solvent was evaporated and water was added to the residue which was extracted with CH2Cl2. The extracts were dried over anhydrous potassium carbonate, filtered, and the solvent was evaporated to leave crude 6-undecanol. The procedure of example 13 a. was followed but the crude 6-undecanol was substituted in place of 9-dodecyn-1-ol to obtain crude 6-undecanyl methanesulfonate. The crude 6-undecanyl methanesulfonate was dissolved in 20 ml acetonitrile and 1 g potassium cyanide were added, as well as 50 mg 18-crown-6, and 100 mg Et4NCN. The mixture was stirred and heated at reflux for 4 days. The mixture was cooled, poured into 5% aqueous NaOH, and extracted with CH2Cl2. The extracts were dried over Na 2 SO4. The extracts were filtered, and the solvent was evaporated. The residue was chromatographed on silica gel eluting with EtOAc-hexanes (2:98) to obtain crude 3-pentylheptanenitrile in low yield. This nitrile was dissolved in 30 ml THF, 1 ml 1M BH3 -THF solution was added, and the mixture was stirred at reflux for 4 hours. Water and 1N NaOH were added. The mixture was concentrated and water was added. The mixture was extracted with CH2Cl2. The extracts were dried over Na2SO4, filtered, and the solvent was evaporated to leave the title compound as an oil (57 mg, 3% yield overall): C12H27N (185.36); 1H-NMR (CDCl3) δ2.64 (d,2), 1.28 (m,17), 0.89 (t,6). Solvent was evaporated water was added to the residue which was extracted with CH2Cl2 The extracts were dried over anhydrous potassium carbonate filtered the solvent was evaporated
