practical and facile strategy for the synthesis of ortho-phosphated (hetero)arylamines from readily available arylhydroxylamines and dialkyl phosphites via cascade Atherton–Todd reaction/[3,3]-rearrangement was developed. This method is amenable to various arylhydroxylamines such as phenylhydroxylamines, naphthylhydroxylamines, and pyridylhydroxylamines, has mild reaction conditions, is oxidant-free, and
开发了一种实用且简便的策略,用于通过级联 Atherton-Todd 反应/[3,3]-重排从现成的芳基羟胺和亚磷酸二烷基酯合成正磷酸化(杂)芳基胺。该方法适用于苯羟胺、萘基羟胺、吡啶基羟胺等多种芳基羟胺,反应条件温和,无氧化剂,具有良好的官能团相容性和优异的区域选择性。
