In one aspect, the disclosure relates to a method for the direct synthesis of complex N,N,O-trisubstituted hydroxylamines by N—O 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.
在一个方面,该公开涉及一种通过N-O键形成直接合成复杂的N,N,O-三取代羟胺的方法。在另一个方面,该方法可以成功地利用各种商业可用的醇和二级胺,并实现构建基于大片段的三取代羟胺文库,用于药物发现目的。还公开了具有低碱性、在常温下高稳定性和固有缺乏对乙酰化和磺酰化酶的反应性的N,N,O-三取代羟胺,这些酶使得较少取代的羟胺具有致突变性。
