Magnesium dialkylamides react with alcohol-derived 2-methyl-2-tetrahydropyranyl alkyl peroxides (MTHPs) in tetrahydrofuran at 0 °C to give N,N,O-trisubstituted hydroxylamines suitable for medicinal chemistry purposes in good to excellent yields. A wide range of secondary alkyl and aryl amines and primary and secondary alcohol-derived MTHPs are compatible with the described reaction which, coupled with the enormous diversity of commercially available alcohols and secondary amines, suggests broad applicability of the reaction in fragment-based library design.
