Chem. 1984,49, 2332-2338) or HO(CH2)2C≡C(CH2)2CH3 (commercially available from GFS Chemicals; Powell, Ohio). Oxidative coupling of HO(CH2)5C≡CH was carried out in a glass reaction vessel by dissolving 6.95 grams of HO(CH2)5C≡CH in pyridine/methanol (2.0 milliliters/6.2 milliliters) and adding 307 grams of CuCl followed by stirring in the presence of oxygen until all the staring material was consumed. The reaction mixture was worked up with diethyl ether and 4N HCl, the combined organic layers were dried over MgSO4, filtered and concentrated. Recrystallization of the residue from 1/1 hexanes/tert-butyl methyl ether to yield 5.35 grams of HO(CH2)5C≡C—C≡C(CH2)5OH as a pink solid. prepared was consumed the combined organic layers were dried over MgSO4 filtered concentrated Recrystallization of the residue from 1/1 hexanes/tert-butyl methyl ether

実験手順: To a slurry of sodium hydride (7.86 g, 197 mmol) in DMF (100 mL) was added methyl iodide (12.29 mL, 197 mmol) followed by a solution of hept-6-yn-1-ol (24.5 g, 197 mmol) in DMF (50 mL). Following the addition the reaction was monitored by TLC. After 2 h additional methyl iodide (6 mL, 50 mmol) was added followed by sodium hydride (1 g, 25 mmol) portions. At 1 h intervals additional sodium hydride (1 g, 25 mmol) portions was added until no alcohol remained as indicated by TLC. Et2O (50 mL) and water (100 mL) was added to the reaction mixture and the layers were separated. The organic layer was washed with brine, dried using Na2SO4, filtered and distilled (145-155° C.) to provide 7-methoxyhept-1-yne (18 g, 121 mmol, 61.7% yield) as a colorless oil. the addition the reaction the layers were separated The organic layer was washed with brine dried filtered distilled (145-155° C.)
