Vorschrift

A mixture of undec-10-yn-1-ol (0.84 g, 5.0 mmol), quinoline (0.13 ml), Lindlar's catalyst (100 mg, 17% w/w) and EtOH (20 mL) was hydrogenated in a Parr apparatus at 50 psi of H2 for 1 h. The mixture was filtered through Celite, and the filtrate was concentrated in vacuo to dryness to give undec-10-en-1-ol (0.86 g, 100%) as a colorless oil, which was used in the next step without further purification: 1H NMR (300 MHz, CDCl3) δ 5.78 (1H, m), 4.92 (2H, m), 3.61 (2H, t, J=6.6 Hz), 2.01 (2H, m), 1.53 (3H, m), 1.21–1.40 (12H, m); 13C NMR (75 MHz, CDCl3) δ 139.43, 114.31, 63.24, 34.00, 32.98, 29.74, 29.61, 29.31, 29.11, 25.92.
