(E)-tridec-2-en-1-ol

反応条件: temp:25.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 2-tridecyn-1-ol (2 g, 10 mmol) in Et2O (50 mL) was added LiAlH4 (1 g, 26 mmol, 2.6 equiv). The resulting mixture was refluxed for 12 hours and allowed to cool to 25° C. A saturated solution of sodium-potassium tartrate was then added and the resulting mixture was stirred for an additional 3 hours. The organic layer was separated, dried (MgSO2) and concentrated by rotary evaporation to yield trans-2-tridecen-1-ol (50) as a colorless oil: 1H NMR (CDCl3) δ 5.62 (dt, J1 =15.3 Hz, J2 =5.1 Hz, 1 H), 5.70 (dt, J1 =15.3 Hz, J2 =5.7 Hz, 1 H), 4.08 (t, J=4.2 Hz, 2 H), 2.04 (q, J=6 Hz, 2 H), 1 30 (m, 16 H), 0.88 (t, J=6.9 Hz, 3 H); 13C NMR (CDCl3) δ 133.72, 128.92, 63.96, 32.31, 32.01, 29.72, 29.60, 29.43, 29.28, 29.24, 22.78, 14.20. ##STR24## The resulting mixture was refluxed for 12 hours The organic layer was separated dried (MgSO2) concentrated by rotary evaporation

実験手順: To dodecyl aldehyde (5.0 g) dissolved in methylene chloride was added (carbomethoxymethylene)triphenylphosphorane (9.1 g), and the mixture was stirred for 2 hours. The reaction mixture was concentrated and subjected to chromatography on a silica gel column with eluent systems of n-hexane-ethyl acetate (from 100:1 to 20:1) to give the methyl ester of trans-2-tetradecenoic acid (5.2 g). To the methyl ester dissolved in tetrahydrofuran was added lithium aluminium hydride (0.9 g) under ice-cooling, and the mixture was stirred for 1 hour. The reaction mixture was distributed into ethyl acetate and water, and the ethyl acetate layer was dried, concentrated and subjected to chromatography on a silica gel column with an eluent system of n-hexane-ethyl acetate (50:1) to give trans-2-tetradecenol (3.2 g). To the solution of the trans-2-tridecenol in methylene chloride were added pyridinium chlorochromate (3.5 g) and Celite (5.0 g), and the mixture was stirred. The reaction mixture was filtered and concentrated to give trans-2-tetradecenal (2.3 g). The reaction mixture was filtered concentrated
