顺-4,顺-7-癸二烯-1-醇

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of triphenylphosphine (20.9 g, 80 mmol) in CH2Cl2 (100 ml) was treated with Br2 (7.8 g, 49 mmol) in CH2Cl2 (15 mL, 0° C.) and the mixture was stirred at room temperature for 20 min. Into the slightly yellow suspension that formed, the crude mixture of 4 and 4Z,7Z)-4,7-decadien-1-ol (12.4 g) in CH2Cl2 (15 ml) was added dropwise. After stirring for 1 hour, a solution of saturated NaHCO3 (50 mL) and water (50 ml) were added. The mixture was extracted with pentane and combined extracts were stored overnight in a freezer. In this way, triphenylphosphine oxide could be crystallized and removed by filtration. Column chromatography followed by distillation at reduced pressure afforded 5 (3.48 g, 32% yield based on 1 of b.p. =80°-85° C./2.5 torr. 1H NMR (200 MHz) δ: 5.37 (m, 4H, CH=CH), 3.41 (t, J=6.6, 6.6 Hz, 2H, CH2 --Br), 2.80 (dd, J=6.4, 6.5 Hz, 2H, =CH--CH2 --CH=), 2.21 (dt, J=7.0, 6.9, 6.8, 6.9 Hz, 2H, CH2 -3), 2.07 (dq, J=7.4 Hz, CH2 -9), 1.91 (tt, J=6.7, 6.6, 7.0, 7.0, 2H, CH2 -2), 0.97 (t, J=7.5, 7.5 Hz, 3H, CH3). 13C NMR (100.6 MHz) δ: 132.1 (8), 129.8 (5), 127.6 (7), 127.0 (4), 33.4 (1), 32.5 (2), 25.6 (3), 25.5 (6), 20.6 (9), 14.3 (10).

Into the slightly yellow suspension that formed the crude mixture of 4 After stirring for 1 hour The mixture was extracted with pentane were stored overnight in a freezer In this way, triphenylphosphine oxide could be crystallized removed by filtration Column chromatography followed by distillation at reduced pressure afforded 5 (3.48 g, 32% yield =80°-85° C./2.5 torr
