Sodium periodate → 2-Oxo-1-(2-oxoethyl)-1,2-dihydroquinoline-7-carbonitrile

Participants

Reaction Steps

A solution of 2-oxo-1-(2-propen-1-yl)-1,2-dihydro-7-quinolinecarbonitrile (600 mg, 2.9 mmol) in 1,4-dioxane (30 ml) and water (20 ml) was cooled to 0° C. and treated with OsO4 (4% in water, 3 ml) and sodium periodate (1.4 g, 6.67 mmol). The reaction was warmed to rt; 0.6 g and then 3.7 g more of sodium periodate were added. After 4 h in total, the solvent was evaporated and residue partitioned between water and 20% methanol-DCM. The phases were separated and the organic phase was dried and evaporated to afford the desired compound (660 mg, 107%).
