with polyphosphoric acid serve as efficient electrophiles in reactions with various nucleophilic amines. Strategically placed second functionality allows for the design of annulation reactions enabling preparation of various heterocycles. This strategy was employed to develop an innovative synthetic approach towards 3,4-dihydroquinazolines from readily available 2-(aminomethyl)anilines.
用多磷酸活化的硝基烷烃在与各种亲核胺的反应中充当有效的亲电子试剂。战略性放置的第二个功能允许设计成环反应,从而能够制备各种杂环。采用该策略开发了一种从容易获得的 2-(氨基甲基)苯胺合成 3,4-二氢喹唑啉的创新方法。
