Reaction Steps
A solution of 4.3 g (20.0 mmol) of sodium periodate and 1.7 g (0.6 mmol) of ruthenium(III) chloride hydrate in 50 ml of water was added to 1.45 g (5 mmol) of 1-tert-butyl 2-methyl 4-(2-fluoroethoxy)pyrrolidine-1,2-dicarboxylate in 80 ml of dichloromethane. The mixture was left at room temperature for three days with vigorous stirring. Subsequently, the phases were separated, the aqueous phase was extracted twice with ethyl acetate (25 ml) and the combined organic phases were stirred with 10 ml of isopropanol for 30 min. The mixture was dried over sodium sulfate, filtered and the solvent was removed in vacuo. The crude product was purified by column chromatography (silica gel, hexane/ethyl acetate). 0.26 g (17%) of 1-tert-butyl 2-methyl 4-(2-fluoroethoxy)-5-oxopyrrolidine-1,2-dicarboxylate (26) was obtained as.
