Reaction Conditions:

with pyridine;4-acetylamino-2,2,6,6-tetramethylpiperidine-N-oxyl;iodine;sodium hydrogencarbonate in dichloromethane;water at 20 - 25; for 3 h;

Steps:

Oxidation of alcohols with the 4-acetamido-2,2,6,6-tetramethylpiperidine-1-oxyl-iodine system.
General procedure: A mixture of 10 mL of 0.1 mol/L solution of sodium hydrocarbonate and 0.084 g (0.4 mmol) of compound 1 were charged into a 50 mL flat-bottom flask equipped with a reflux condenser and a magnetic stirrer. 4 mmol of an alcohol dissolved in 10 mL of methylene chloride (alcohol-nitroxyl 1 molar ratio1 : 0.1) was added to the solution, and then 0.4 mmolof an amine was introduced (alcohol-amine 1 : 0.1; 1-amine 1 : 1). 2.0 g (8 mmol) of crystalline iodine was added at vigorous stirring to the two-phase system; the mixture was stirred during 3 h at 20-25° and then treated with 20% solution of sodium thiosulfate for elimination of excess iodine. Aqueous and organic layers were separated, and the product was additionally extracted from the aqueous layer with methylene chloride (2×10 mL). The organic phases were combined and analyzed by means of chromatography.
