実験手順
A mixture of (R)-4-(prop-1-en-2-yl)cyclohex-1-enecarbaldehyde (0.574 g, 3.82 mmol), 1-(1-isocyanoethylsulfonyl)-4-methylbenzene (0.80 g, 3.82 mmol), and K2CO3 (1.06 g, 7.65 mmol) in MeOH (25 mL) was heated at reflux for 2 h. The reaction mixture was cooled to ambient temperature, concentrated in vacuo, and diluted with EtOAc. The organic solution was washed with water, separated, and concentrated in vacuo. The residue was chromatographed on silica gel with EtOAc/hexanes (0%-35%) to isolate 0.54 g (70%) of the title compound as an oil. 1H NMR (300 MHz, DMSO-d6) δ 8.12 (s, 1H), 6.15-6.06 (m, 1H), 4.74 (s, 2H), 2.47-2.25 (m, 3H), 2.24-2.00 (m, 5H), 1.94-1.82 (m, 1H), 1.74 (s, 3H), 1.59-1.40 (m, 1H). MS (DCI+) m/z 204 (M+H).
