实验步骤: 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

实验步骤: 1-Bromo-2-tridecyne (colorless oil) was prepared from 2-tridecyn-1-ol using the CBr4/triphenylphosphine mixture in dichloromethane to carry out the halogenation. 1-Bromo-2-tridecyne (colorless oil) was thus formed with a yield of 91%.

实验步骤: A process for preparing the sex pheromone of Lymantria dispar L. effectively which comprises the steps of reacting 1-bromodecane and propargyl alcohol tetrahydropyranylether in the presence of sodium hydroxide to give 1-tetrahydropyranyloxy-2-tridecyne, treating the tetrahydropyranyloxy-2-tridecyne with p-toluenesulfonic acid to give 2-tridecyn-1-ol, catalystic-hydrogenating the 2-tridecyn-1-ol in the presence of Lindlar catalyst to give (Z)-2-tridecen-1-ol, oxidizing the (Z)-2-tridecen-1-ol with peroxide to give (±)-cis-2,3-epoxy-1-tridecanol, reacting the (±)-cis-2,3-epoxy-1-tridecanol with acid anhydride in the presence of hydrolase in an organic solvent for a stereoselective acylation and recovering unreacted optically active (2R, 3S)-cis-2,3-epoxy-1-tridecanol after the acylation, reacting the optically active (2R, 3S)-cis-2,3-epoxy-1-tridecanol with toluenesulfonylchloride to give (2R, 3S)-cis-1-p-toluenesulfoxy-2,3-epoxytridecane, and reacting the (2R, 3S)-cis-1-p-toluenesulfoxy-2,3-epoxytridecane with di(4-methylpentyl) lithium copper reagent to yield (7R, 8S)-cis-2-methyl-7,8-epoxyoctadecane which is the sex pheromone of Lymantria dispar L.
