Participants

Reaction Steps

To a solution of [(2R,3R,4S,5R,6S)-3,4,5-tribenzyloxy-6-[4-chloro-3-[(4-ethoxy-2,3-difluoro-phenyl) methyl]phenyl]-6-methoxy-tetrahydropyran-2-yl]methanol 23j (4.20 g, 5.64 mmol) in dichloromethane (70 mL) was added 2-iodoxybenzoic acid (4.70 g, 16.91 mmol) at room temperature. The mixture was refluxed for 36 hours. The reaction mixture was cooled to room temperature and filtered. The filtrate was washed with saturated sodium chloride (50 mL×3), dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated in vacuo to give the title compound 23k as a yellow solid (4.12 g, 97.8%). This material was not further purified.
