PROCEDURE
实验过程
In a round-bottom flask equipped with a stir bar and under an atmosphere of argon was added KH (4.46 g, 111 mmol). The flask was cooled to 0° C. and 1,3-diaminopropane (50 mL) was added slowly via syringe. The solution was stirred for 45 min. Then 2-nonyn-1-ol, dissolved in of 1,3-diaminopropane (30 mL), was added dropwise via syringe to the stirring solution. The reaction was stirred for an additional 30 min at 0° C. before warming to room temperature overnight. The reaction was again cooled to 0° C. before quenching with water. The compound was extracted with Et2O, washed with HCL, water, and brine, dried with MgSO4, and concentrated. This produced 4.94 g of dark orange oil which was purified by flash column chromatography on silica gel (2.5% Et2O in hexane to 50% Et2O in hexane) to give 3.21 g of clear oil (67%): IR (near) ν 3409, 2931, 2242 cm−1, 1H—NMR δ 3.59 (t, 2H, J=7.0 Hz), 2.14 (td, 2H, J=3.0 Hz, 7.0 Hz), 2.10 (s, 1H), 1.91 (t, 1H, J=3.0 Hz), 1.50 (bm, 4H), 1.30 (bm, 6H); 13C—NMR δ 84.6, 68.1, 62.8, 32.6, 28.8, 28.6, 28.3, 25.6, 18.3; MS m/z 147.10 (M++Li). Anal. Calcd for C9H16O: C, 77.09; H, 11.46. Found: C, 77.00; H, 11.46.
