실험 절차

Compound 494 (0.033 g, 0.09 mmol) was suspended in MeOH (1 mL). 3-Hydroxy-butyraldehyde (0.023 g, 0.27 mmol) and NaCN(BH3) (0.055 g, 0.88 mmol) were added. The suspension was stirred at room temperature for 18 h. 3-Hydroxy-butyraldehyde (0.023 g, 0.27 mmol) and NaCN(BH3) (0.055 g, 0.88 mmol) were added again and the suspension was stirred at room temperature for 24 h. The reaction mixture was concentrated in vacuo. The residue was dissolved in EtOAc and the organic phase was washed with brine. The water phase was extracted with EtOAc and the combined organic phases were dried (MgSO4), filtered and concentrated in vacuo. The crude product was purified by flash chromatography using MeOH/CH2Cl2 1:50 as the eluent. This afforded the title compound as oil. 13C NMR (CDCl3) δ 196.7, 159.0 (dd), 155.4 (dd), 147.3, 146.0, 139.6, 135.0, 133.5, 132.0, 129.9, 126.7, 124.6 (dd), 124.0 (dd), 116.3, 115.9, 114.6, 112.8, 111.6 (dd), 104.9 (dd), 67.5, 42.1, 38.0, 24.0, 19.4
