Participants

Reaction Steps

(Step 1) To Compound 8 (16 mg, 0.037 mmol), dichloromethane (1.8 mL), tert-butyl 2-hydroxyacetate (5.8 mg, 0.044 mmol), EDC.HCl (10.5 mg, 0.055 mmol), and DMAP (0.4 mg, 0.0037 mmol) were added, and the resulting mixture was stirred at room temperature for 4 days. The solvent was evaporated under reduced pressure, and the resulting residue was purified by thin-layer column chromatography (ethyl acetate/n-hexane=1/9), whereby 1-(2-tert-butoxy-2-oxoethyl) 5-tert-butyl (Z)-2-methyl-4-{(E)-2,4,6,8,10-pentamethyldodec-2-enylidene}pentanedioate (14.7 mg, 73%) was obtained.
