The condensation of α-hydroxyaminoalcohols with aldehydes and acetone gave 3-hydroxyoxazolidines and tautomeric N-(2-hydroxyethyl)-α-arylnitrones, whose oxidation by PbO2 in methanol leads to stable oxazolidine nitroxyl radicals with methoxy groups at Cs

Anodic oxidation of N-alkylhydroxylamines with and without a β-hydroxy group was studied by cyclic voltammetry and controlled potential electrolysis in aqueous buffer solution of pH 8.8.The hydroxylamines with a β-hydroxy group were oxidized initially to the corresponding nitroxides and gave the final products via two routes; i) cleavage of the (α)C-(β)C bond to give aldehydes and oximes, and ii) disproportionation of the nitroxides to form the nitroso compounds.The hydroxylamines without a β-hydroxy group did not undergo cleavage of the (α)C-(β)C bond and gave nitroso compounds.Substituents on the α and β carbons affected the product distribution.When a phenyl group or two methyl groups were present on the (β)C, or one methyl group was present on both (α)C and (β)C, (α)C-(β)C bond cleavage was predominant.
