Procedure

1,8-Diazabicyclo[5.4.0]-7-undecene (0.1 mL) was added to a solution (10 mL) of methyl 2-((E)-1-propenyl)cinnamate (102 mg, 0.50 mmol) in nitromethane, followed by-stirring at room temperature for 3 hours. Next, the reaction solution was added to a saturated aqueous solution of sodium bicarbonate under ice-cooling to neutralize the reaction solution, and the mixture was then extracted with diethyl ether. After the extract was washed with a saturated brine and then dried over sodium sulfate, the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (developed with diethyl ether/hexane=1/4) to give methyl 3-[2-((E)-1-propenyl)phenyl]-4-nitrobutyrate (52 g, yield 40%).
