実験手順

A solution of 8a (0.05 g, 0.13 mmol), methanesulfonyl chloride (1 mL) and NEt3 (2 mL) in CH2Cl2 (30 mL) was stirred at room temperature overnight and then the mixture was washed with saturated NaHCO3 (20 mL) and saturated NaCl (2×15 mL) and dried (Na2SO4). The solvent was removed under reduced pressure. The resulting crude solid was purified by column chromatography (eluent: ethyl acetate/n-hexanes) to afford 0.02 g (32%) of a white solid, mp 147-150° C.; 1H NMR (CDCl3): δ 1.14 (3H, s, H-19); 1.47 (3H, s, H-20); 1.50-1.70 (3H, m, H-7α,β and H-11β); 1.81 (1H, m, H-6α); 2.11 (1H, dd, J=2.9, 11.3 Hz, H-8); 2.16 (1H, s, H-10); 2.19 (1H, m, H-6β); 2.42 (1H, dd, J=13.2, 13.2 Hz, H-3α); 2.50 (1H, m, H-3β); 2.52 (1H, dd, J=4.8, 13.2 Hz, H-11α); 2.75 (1H, dd, J=3.6, 13.2 Hz, H-4); 3.25 (3H, s, CH3SO2); 3.74 (3H, s, CO2CH3); 5.07 (1H, dd, J=8.0, 12.2 Hz, H-2); 5.55 (1H, dd, J=5.1, 11.7 Hz, H-12); 6.41 (1H, dd, J=0.9, 1.8 Hz, H-14); 7.42 (1H, dd, J=1.8, 1.8 Hz, H-15); 7.45 (1H, br d).
