Participants

Reaction Steps

A solution of EXAMPLE 180A (2.80 g) in dioxane/water (30 mL/10 mL) was added to 2,6-dimethylpyridine (1.909 mL) and sodium periodate (7.02 g) followed by the addition of osmium tetroxide (2.5% solution, 1.0 mL) and the reaction mixture was stirred for 30 minutes at room temperature. The reaction mixture was diluted with ethyl acetate (50 mL), washed with water (50 mL) and brine (50 mL), dried over magnesium sulfate, filtered, and concentrated. The residue was dissolved in methanol (20 mL) and sodium borohydride (0.16 g) was added. The mixture was stirred at room temperature for 1 hour. An aqueous work up followed by silica gel chromatography using 2-30% ethyl acetate in hexanes provided the title compound.
