实验步骤: Compound 102-1 (2.50 g) was dissolved in methylene chloride (60 ml), triphenylphosphine (4.86 g) and N-chlorosuccinimide (2.84 g) were added under ice-cooling, and the mixture was stirred under ice-cooling for 1 hr. Triphenylphosphine (4.86 g) and N-chlorosuccinimide (2.84 g) were further added, and the mixture was stirred for 1 hr. Water was added to the reaction mixture, and the mixture was extracted with methylene chloride and washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. Diethyl ether (100 ml) was added, and the precipitated triphenylphosphine oxide was filtered off. The concentrate of the filtrate was purified by silica gel column chromatography (hexane:ethyl acetate) to give the object product (1.20 g) as a colorless oil. cooling cooling for 1 hr the mixture was stirred for 1 hr the mixture was extracted with methylene chloride washed with saturated brine dried over anhydrous sodium sulfate The solvent was evaporated under reduced pressure Diethyl ether (100 ml) was added the precipitated triphenylphosphine oxide was filtered off The concentrate of the filtrate was purified by silica gel column chromatography (hexane:ethyl acetate)

实验步骤: 3-(4-Methylphenyl)acrylic acid (5.0 g) was dissolved in methanol (30 ml), concentrated sulfuric acid (0.5 ml) was added, and the mixture was stirred at 100° C. for 2.5 hr. The reaction mixture was concentrated, and the residue was washed with water. The obtained white solid was dissolved in tetrahydrofuran (120 ml), 1M diisobutylaluminum hydride/toluene solution (67 ml) was added dropwise at −78° C., and the mixture was stirred as it was at −78° C. for 2 hr. Saturated aqueous ammonium chloride solution was added to the reaction mixture, and the mixture was stirred at room temperature. Aluminum salt was collected by filtration through celite, extracted with methylene chloride, washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate) to give the object product (3.84 g) as a white powder. The reaction mixture was concentrated the residue was washed with water The obtained white solid was dissolved in tetrahydrofuran (120 ml) 1M diisobutylaluminum hydride/toluene solution (67 ml) was added dropwise at −78° C. the mixture was stirred as it was at −78° C. for 2 hr Saturated aqueous ammonium chloride solution was added to the reaction mixture the mixture was stirred at room temperature Aluminum salt was collected by filtration through celite extracted with methylene chloride washed with saturated brine dried over anhydrous sodium sulfate The solvent was evaporated under reduced pressure The residue was purified by silica gel column chromatography (hexane:ethyl acetate)

实验步骤: To a solution of 2.5 g. p-methylcinnamyl alcohol in 50 ml. ether at 0° under nitrogen is added 4.9 g. 9-cyclopropylnonanoyl chloride and 3.6 ml. pyridine. The reaction mixture is allowed to warm to room temperature and is then stirred for ten days. Water is then added to dissolve the pyridinium hydrochloride and form a second liquid phase. This mixture is stirred for 4 hours to hydrolyze the excess acid chloride and the mixture is then diluted with a mixture of ether and water. The ether phase is separated and the aqueous phase is extracated once with ether. The combined ether phases are washed with 2N sulfuric acid, 10% potassium carbonate, water, saturated copper sulfate, water, and brine, dried over calcium sulfate and the solvent removed to yield p-methylcinnamyl 9-cyclopropylnonanoate. form a second liquid phase This mixture is stirred for 4 hours The ether phase is separated The combined ether phases are washed with 2N sulfuric acid, 10% potassium carbonate, water, saturated copper sulfate, water, and brine dried over calcium sulfate the solvent removed
