실험 절차

To a solution of Example 1 (11.86 g) in dichloromethane (100 mL) was added triethylamine (TEA) (19.6 mL, 4 equivalents) followed by dropwise addition of vinylbenzenesulfonyl chloride (8.36 g, 1.2 equivalents) at 25° C. for 3 hrs. The mixture was partitioned in 1N sodium bicarbonate (NaHCO3) and ethyl acetate (EtOAc). The organic extract was concentrated, and the residue was chromatographed on silica gel, eluting with ethyl acetate/hexanes (1:4) to afford the title compound (9.6 g, 54%). 1H NMR (300 MHz, CDCl3): δ ppm 0.87 (d, J=6.44 Hz, 3H), 0.90 (d, J=6.78 Hz, 3H), 1.34 (s, 9H), 1.86 (m, 1H), 2.84 (dd, J=13.39, 6.61 Hz, 2H), 2.97 (m, 3H), 3.11 (m, 3H), 3.79 (s, 1H), 4.61 (s, 1H), 5.44 (d, J=10.85 Hz, 1H), 5.88 (d, J=17.63 Hz, 1H), 6.75 (dd, J=17.63, 10.85 Hz, 1H), 7.25 (m, 5H), 7.51 (d, J=8.48 Hz, 2H), 7.72 (d, J=8.48 Hz, 2H).
