실험 절차

To a solution of 1-[3-(tert -butyldimethylsilanyl)prop-2-ynyl]-4-(1-hydroxy-2-phenylethyl)-6-iodo-3-methyl-1H-pyridin-2-one 4a (60 mg, 0.12 mmol) and 4-dimethylaminopyridine (2 mg, 1.2 μmol) in CH2Cl2 (2 mL) was added NEt3 (49 mg, 66 μL, 0.48 mmol) and chlorodimethyloctylsilane (62 mg, 77 μL, 0.3 mmol). The resulting mixture was stirred for 12 h. The solvent was evaporated and the residue was purified by flash chromatography (hexanes-EtOAc 15:1) to afford 5a (41 mg, 51%) as a yellow oil. 1H NMR (300 MHz, CDCl3) δ7.32-7.24 (m, 3H), 7.15-7.12 (m, 2H), 7.08 (s, 1H), 5.14 (d, J=17.0, 1H), 5.09 (d, J=17.0, 1H), 4.79 (t, J=6.4 Hz, 1H), 2.79 (d, J=6.4 Hz, 2H), 1.98 (s, 3H), 1.39-1.11 (m, 14H), 0.94 (s, 9H), 0.90-0.87 (m, 3H), 0.10 (s, 6H), −0.17 (s, 3H), −0.18 (s, 3H); 13C NMR (75 MHz, CDCl3) δ162.3, 152.0, 137.8, 129.7, 129.1, 128.3, 127.5, 127.2, 126.6, 118.6, 88.4, 44.6, 33.5, 32.0, 29.4, 29.3, 26.1, 23.2, 23.0, 22.7, 17.9, 16.5, 14.2, 12.0, −0.19, −2.05, −4.78.
