实验过程

A mixture of methyl 2-(allyl)-6-(3-chloro-4-fluorobenzyl)-4-methoxy-3,5-dioxo-2,3,5,6,7,8-hexahydro-2,6-naphthyridine-1-carboxylate (0.20 g, 0.46 mmol), N-methylmorpholine N-oxide (67 mg, 0.58 mmol), water (0.2 mL), and osmium tetroxide (0.75 mL, 0.08 M in t-butanol) in acetone (1 mL) was stirred at room temperature overnight. The product mixture was concentrated under vacuum. The residue was subjected to column chromatography on silica gel. Collection and concentration of appropriate fractions provided the title compound.
