silica gel; In tetrapropylammonium perruthennate; dichloromethane; | EXAMPLE 219A 3-methyl-4-nitrobenzaldehyde To a solution of <strong>[80866-75-7]3-methyl-4-nitrobenzyl alcohol</strong> (3.0 g, 18 mmol), N-methylmorpholine-N-oxide (3.2 g, 27 mmol), and powdered 4A molecular sieves (8.98 g) in methylene chloride (40 mL) was added in one portion tetrapropylammonium perruthenate (0.315 g, 0.898 mmol), and the reaction stirred at room temperature. The reaction was filtered through silica gel, eluding with methylene chloride, solvent evaporated and the residue purified by flash chromatography to provide 2.2 g of the title compound.

silica gel; In dichloromethane; | Part B. Preparation of N-(benzyloxycarbonyl)-3-pyrrolidinone. To a stirring solution of N-(benzyloxycarbonyl)-3-pyrrolidinol (1600 mg, 7.2 mmol) and 4-methylmorpholine oxide (1269 mg, 10.8 mmol, Aldrich) in dry CH2Cl2 (100 mL) with activated molecular sieves (1000 mg) was added tetrapropylammonium perruthenate (127 mg, 0.36 mmol, Aldrich). The reaction was stirred for 1 h and then filtered through a pad of silica gel. The silica gel was washed with EtOAc (500 mL). The organic filtrates were combined and conc. in vacuo to a colorless oil of pure N-(benzyloxycarbonyl)-3-pyrrolidinone. MS (ESI) 220 (M+H). |
