実験手順
To a solution of 5,8-dichloro-2,3,4,9-tetrahydro-1H-carbazol-1-one (0.1 g, 0.39 mmol) in anhydrous THF (8 mL) at 0° C., CsF (59 mg, 0.39 mmol) and CF3TMS (0.56 g, 3.93 mmol) were added. The reaction mixture was slowly warmed to room temperature and stirred for 18 h. After the volatiles were removed in vacuo, the residue was diluted with water and extracted with EtOAc (2×15 mL) to give the crude compound which was purified by silica gel chromatography [EtOAc-hexane (1:4) as eluant] to give the title compound (0.127 g, 16%). 1H NMR (500 MHz, DMSO-d6, δ in ppm) 11.07 (s, 1H), 7.21 (d, J=8.0 Hz, 1H), 7.06 (d, J=8.5 Hz, 1H), 6.62 (s, 1H), 3.01-3.0 (m, 2H), 2.22-2.19 (m, 1H), 1.97-1.92 (m, 3H).
