실험 절차

Cinnamyl alcohol (270 mg, 2.0 mmol) was dissolved in benzene (1 mL), added with aluminum isopropoxide (40 mg, 0.1 eq, 0.20 mmol) and 2-nitrobenzaldehyde (390 mg, 1.3 eq, 2.6 mmol) and stirred at room temperature for 1 hour. The reaction mixture was added with ethyl acetate and made acidic with addition of 2 N hydrochloric acid, and then the organic layer was separated. Subsequently, the organic layer was washed with saturated brine and dried over magnesium sulfate. The solvent was evaporated in vacuo, and the residue was purified by silica gel column chromatography (hexane:ethyl acetate=30:1) to obtain 260 mg (yield: 97%) of the title compound as yellow oil.
