Diversity-oriented synthesis of N,N,O-trisubstituted hydroxylamines from alcohols and amines by N—O bond formation

In one aspect, the disclosure relates to a method for the direct synthesis of complex N,N,O-trisubstituted hydroxylamines by NO bond formation. In another aspect, the method can successfully be employed using a wide variety of commercially available alcohols and secondary amines and enables the construction of large fragment-based libraries of trisubstituted hydroxylamines for drug discovery purposes. Also disclosed are N,N,O-trisubstituted hydroxylamines having low basicity, high stability at ambient temperatures, and an inherent lack of reactivity towards acetylating and sulfonylating enzymes that confer mutagenicity on less-substituted hydroxylamines.
