Procedure
A solution of cyclohex-1-enecarboxylic acid methyl ester 1 (5.15 g; 36.7 mmol), tetrabutyl ammonium fluoride (55.10 mL; 1 M in THF; 55.1 mmol) and nitromethane (3.97 mL; 73.5 mmol) in tetrahydrofuran (60 mL) was heated to reflux for 4 hours. After cooling to room temperature, the reaction mixture was diluted with diethyl ether (500 mL), washed with 2N HCl (2×100 mL) and then with brine (2×100 mL). The phases were separated. The organic phase was dried over MgSO4 and concentrated in vacuo. The crude mixture was purified over silica gel chromatography (EtOAc/heptane 1:4) to give 2 (5.46 g; cis and trans isomers; 73%) as a pale yellow liquid.
