実験手順
To a solution of compound 3a (1.60 g, 7.7 mmol) in dry DCM (30 mL) was added Dess-Martin periodinane (6.5 g, 15.4 mmol) at 0° C. and the mixture was stirred at rt for 2 h under N2 atmosphere. The mixture was quenched with saturated sodium bicarbonate solution and diluted with EA. The organic portion was washed with brine, dried over Na2SO4, filtered, concentrated under reduced pressure and purified by CC (PE/EA=4:1) to give compound 3 (1.2 g, 75%) as a white solid.
