Crude AEW 272-2 (6.12 g, 20.3 mmol, 1 equiv.) was dissolved in anhdrous CH­2Cl2 (203 mL) and (diacetoxyiodo)benzene (6.60 g, 20.3 mmol, 1 equiv.) was added. The reaction mixture was stirred at rt for 3 h and then quenched by the addition of a saturated aqueous solution of sodium hydrogen carbonate. Aqueous layers were separated and then extracted with CH­2Cl2 and then organic layers were combined and washed with brine (× 1), dried (MgSO4), filtered and evaporated. The crude mixture was then purified by

NMR
