실험 절차

A 140 mg sample of 82 (0.23 mmol) was dissolved in CH2Cl2 (4 mL) and treated with DMBA (35.4 mg, 0.26 mmol) and Pd(PPh3)4 (32 mg, 0.028 mmol). The solution was stirred at 0° C. for 15 mins, warmed to room temperature for 2 hours, then diluted with CH2Cl2 and washed with water (2×) and brine. The solvent was concentrated in vacuo and the residue purified by flash chromatography on silica gel using MeOH/CH2Cl2 (1/99 to 3/97) to give the title compound (93.2 mg, 71% yield). 1H-NMR (500 MHz, CD3OD) δ 1.16 (d, 0.25H), 1.28-1.49 (m, 2.75H), 1.63-2.33 (m, 4H), 2.48 (dd, 0.4H), 3.39-3.59 (m, 0.2H), 3.60-3.73 (m, 0.8H), 3.73-3.96 (m, 1H), 4.24-4.48 (m, 2H), 4.57-4.92 (m, 7H), 5.44 (s, 0.4H), 5.50 (d, 0.4H), 5.64 (d, 0.8H), 5.75 (d, 0.5H), 7.16-7.43 (m, 5H), 7.78-7.8.9 (m, 1.6H), 8.40-8.63 (m, 0.4H). Analytical HPLC (cyano column) (mixture of 2 diastereomers) 11.57, 11.82 min. LC-MS (ES+) m/e=564.1 (M+H)
