実験手順

Compound 30 (0.25 g, 1.0 mmol) was dissolved in nitrobenzene (5 mL). AlCl3 (0.6 g, 4.5 mmol) and then isobutyroyl chloride (0.6 mL, 5.7 mmol) were added in portions. The reaction mixture was stirred for 40 min (LC/MS monitoring). The obtained mixture was poured into ice/water mixture and extracted with CHCl3. The combined extracts were evaporated, and the residue was purified by chromatography in a short thick silica gel column (eluent: CHCl3/MeOH 99:1→90:10) to afford 0.189 g (47%) of the product. 1H NMR (DMSO-d6): δ 1.20 (12H, d, J=6.7 Hz); 1.90-1.97 (2H, m); 2.11 (6H, s); 2.18 (2H, t, J=6.7 Hz); 3.91 (2H, septet, J=6.7 Hz), 4.50 (2H, t, J=6.6 Hz); 7.76 (2H, d, J=8.7 Hz); 8.14 (2H, dd, J=8.7 Hz, J=1.5 Hz); 9.11 (2H, d, J=1.5 Hz). ELSD: 100%, ESI-MS: m/z 392 [M+H]+.
