Abstract
The invention concerns a method for chemoselective oxidation of an organic compound comprising several potentially oxidizable groups whereof at least one is a nitrogen group. Said method is characterised in that it consists in using at least a protic solvent, which is a good donor of hydrogen bonds, enabling to limit N-oxidation.
