Reaction Steps

The product from Step B (0.275 g, 1.01 mmol) was dissolved in ethyl acetate (5 mL). A solution of sodium periodate in water (0.5 g in 5 mL) and ruthenium tetroxide (13 mg, 0.10 mmol) was added, and the heterogeneous reaction stirred vigorously overnight at room temperature. An additional portion of sodium periodate in water was added (0.5 g in 5 mL) and the reaction stirred overnight. The reaction was quenched with 10% sodium thiosulfate, and filtered through celite. The phases were separated, and the organic phase dried over magnesium sulfate. Filtration and evaporation gave the title compound.
