Reaction Steps

Into a solution of 2 (1.25 g, 3.61 mmol) in CHCl3 (25 mL) was added 5 (0.66 g, 3.61 mmol), EEDQ (1.07 g, 4.32 mmol), and triethylamine (0.74 mL, 5.33 mmol). The solution was stirred at reflux for 19 h before cooling to RT and adding EtOAc. The solution was washed sequentially with 1N HCl, 0.1N NaOH, water, and brine, before drying over MgSO4 and concentrating under reduced pressure. The crude material was purified on a silica gel column eluted with 20% moving to 50% EtOAc in hexanes. Combined and concentrated pure fractions. to give 6 (0.33 g, 18%). MS: APCI (AP+): 510.3 (M)+, (AP−): 508.4 (M)−.
