Versuchsvorschrift

Into a solution of 6 (0.250 g, 1.02 mmol) in CHCl3 (10 mL) was added 7 (0.212 g, 1.02 mmol), EEDQ (0.302 g, 1.22 mmol), and triethylamine (0.213 mL, 1.53 mmol). The solution was stirred at reflux for 19 h before cooling to RT and adding EtOAc. The solution was washed sequentially with 10% aq. citric acid, 1N NaOH, water, and brine, before drying over MgSO4 and concentrating under reduced pressure. The crude material was purified by flash chromatography to reveal 8 (0.329 g, 74%) as a tan foam. MS: APCI (AP+): 436.1 (M)+, (AP−): 434.1 (M)−.
