실험 절차

Under a nitrogen atmosphere, methyl 9-oxo-hexadecanoate (No. 4984860; 2.39 g, 8.40 mmol) was dissolved in dichloromethane (47 mL), and the solution was cooled to 0° C. While maintaining the temperature at 0° C., 1,2-ethanedithiol (840 μL, 10.1 mmol), and borontrifluoride-ethylether complex (1.24 mL, 10.1 mmol) were sequentially added, and the mixture was stirred at 0° C. for 5 minutes and at room temperature for 2 hours. Water was added to the reaction solution to stop the reaction, and the solution was extracted with dichloromethane. The organic layer was sequentially washed with a saturated sodium bicarbonate aqueous solution and a saturated brine, and dried over anhydrous sodium sulfate. After the organic layer was filtered and the solvent was distilled off, the resulting residue was purified with SP1 (SiO2 cartridge, 5.0% ethyl acetate/n-hexane, Rf=0.5) to obtain methyl 8-(2-heptyl-[1,3]dithiolan-2-yl)-octanoate (No. 5553355; 2.57 g, 85% yield).
