Versuchsvorschrift

To a solution of (6Z,16Z)-12-((Z)-dec-4-enyl)docosa-6,16-dien-11-ol 8 (0.4 g, 0.9 mmol), 4-(dimethylamino)butanoic acid hydrochloride (0.2 g, 1.3 mmol), EDCI hydrochloride (0.25 g, 1.3 mmol), diisopropylethylamine (0.4 mL, 2.6 mmol) in anhydrous dichloromethane (10 mL) was added dimethylaminopyridine (5 mg). The solution was refluxed for 2 hours then stirred at room temperature for 2 hours. The mixture is concentrated in vacuo to dryness and purified by column chromatography (100% ethyl acetate) to afford 6Z,16Z)-12-((Z)-dec-4-enyl)docosa-6,16-dien-11-yl 4-(dimethylamino)butanoate 9 as a pale yellow oil. 1H NMR (400 MHz, CDCl3) δ 5.36 (m, 6H), 4.93 (m, 1H), 2.30 (m, 4H), 2.22 (s, 6H), 2.03 (m, 12H), 1.88 (m, 2H), 1.66-1.18 (m, 31H), 0.90 (m, 9H). Rf 0.3 (10% MeOH—CH2Cl2).
