Participants

Reaction Steps

To a stirred solution of acetic acid (5S,6S,7R,8S)-6,7-diacetoxy-5-[4-chloro-3-(3,4-dihydro-2H-benzo[1,4]oxazin-6-ylmethyl)-phenyl]-4-oxa-spiro[2.5]oct-8-yl ester (100 mg, 0.18 mmol) in methanol (6 mL) was added sodium methoxide (39 mg, 0.73 mmol) and stirred at room temperature for 3 h. The solvent was evaporated and crude product purified by silica gel column chromatography to give 35 mg of (5S,6R,7R,8S)-5-[4-chloro-3-(3,4-dihydro-2H-benzo[1,4]oxazin-6-ylmethyl)-phenyl]-4-oxa-spiro[2.5]octane-6,7,8-triol as a white solid.
