is presented. In the presence of Pd(PPh3)4, accessible precursors undergo a Suzuki cross-coupling reaction with 2-(Boc-amino)benzeneboronic acid pinacol ester and then spontaneously undergo deprotection and intramolecular condensation to form the corresponding phenanthridines in one step. This reaction has a wide range of substrates with various functional groups, and the corresponding products have
提出了一种一锅合成取代菲啶的通用方法的发现和发展。在Pd(PPh 3)4存在下,可及的前体与2-(Boc-氨基)苯硼酸频哪醇酯进行Suzuki交叉偶联反应,然后自发进行脱保护和分子内缩合以形成相应的菲啶。该反应具有多种具有各种官能团的底物,并且已经以良好的产率获得了相应的产物。
