Reaction Steps

1-[(3aR,4R,6R,6aR)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxol-4-yl]pentane-1,3-dione 1-oxime (0.5 g) was dissolved in aqueous acetic acid (18 mg) and the mixture heated at 100° C. for 2 h. The solution was cooled and concentrated in vacuo to afford a brown oil which was azeotroped with toluene. Purification by chromatography on silica gel (Varian Bondelut silica gel cartridge), eluting with (i) dichloromethane, (ii) ether, (iii) ethyl acetate, (iv) methanol, gave the title compound (150 mg).
