实验步骤: 5-octylsalicylaldehyde was prepared as follows: p-octyl phenol (20.6 g) was dissolved in dry methylene chloride (400 cm3). The solution was cooled in an ice bath, stirred and treated carefully with titanium tetrachloride (44 cm3). 1,1-Dichloromethyl methyl ether (30 cm3) was then added dropwise to the cooled stirred solution. After the addition was complete, the temperature was raised to 40° C. and stirring continued for a further 15 minutes. The mixture was then poured into crushed ice (500 g) and the organic layer extracted with ether. The ethereal solution was washed several times with water, dried over anhydrous sodium sulpate and evaporated. The oily residue was purified by fractional distillation under vacuum to give 5-octylsalicylaldehyde as a colourless liquid which solidified at 30° C. 5-octylsalicylaldehyde was prepared The solution was cooled in an ice bath stirred solution After the addition stirring The mixture was then poured the organic layer extracted with ether The ethereal solution was washed several times with water dried over anhydrous sodium sulpate evaporated The oily residue was purified by fractional distillation under vacuum

实验步骤: To a solution of 2.06 g (10 mmol) of 4-octylphenol in 50 mL of THF was added 0.85 g (15 mmol) of powdered KOH and 3.98 g (15 mmol) of 18-crown-6. The solution was heated to 50° C. for 15 minutes, whereupon 2.8 g (15 mmol) of methyl 4,4-diethoxy-2-butynoate was added. The mixture was stirred for 30 minutes, then allowed to cool to room temperature. The solution was then poured into water, and extracted 3 times with 40 mL of ethyl acetate. The organic layers were combined, dried (MgSO4) and concentrated. The crude oil was subjected to column chromatography on SiO2. Elution with 20% ethyl acetate-hexane yielded 2.1 g (54%) of an oil, used in the next step without further purification. was added extracted 3 times with 40 mL of ethyl acetate dried (MgSO4) concentrated Elution with 20% ethyl acetate-hexane
