実験手順
Dess-Martin periodinane (47 mg, 0.11 mmol) was added to a solution of alcohol 58-a (0.079 mmol) in anh. DCE (3 ml). The reaction mixture was stirred at room temperature for 90 min and then quenched with 10% aq. Na2S2O3 and aq. NaHCO3 (sat.). The phases were separated and the organic layer was dried (Na2SO4) and concentrated. Purification by flash column chromatography (EtOAc/iso-Hexane, 0:100-40:60) gave the title compound (6.5 mg, 13%). MS m/z 660.1 (M+H)+.
