Reaction Steps
(3R,4S,5R)-5-(5-ethylisoxazol-3-yl)tetrahydrofuran-2,3,4-triol isomer 1 (150 mg) was dissolved in pyridine (4 ml) and the mixture treated with acetic anhydride (0.983 ml). The resulting solution was stirred at 22° C. for 18 h. The mixture was concentrated in vacuo to afford a brown oil. Purification by chromatography on silica gel (Varian Bondelut SiO2 cartridge), eluting with (i) dichloromethane, (ii) ether (iii) ethyl acetate, afforded the title compound as a pale yellow solid (142 mg).
