  A practical method for the synthesis of 6-aroyl phenanthridine derivatives by Fe-catalyzed oxidative radical cyclization of 2-isocyanobiphenyls with benzylic alcohols is described. In addition, this cyclization could be occurred by using toluene as aroyl source. The procedure tolerates various functional groups under simple conditions. A single-electron-transfer pathway is proposed according to mechanistic

  2-isocyanobiphenyls react with aromatic aldehydes via base promoted homolytic aromatic substitution (BHAS) to give 6-aroylated phenanthridines. Reactions occur via addition of acyl radicals to the isonitrile functionality and subsequent intramolecular BHAS of the intermediate imidoyl radicals. Initiation of the radical chain reaction is best achieved with small amounts of FeCl3 (0.4 mol %), and the commercially

  易于获得的2-异氰基联苯通过碱促进的均相芳族取代（BHAS）与芳族醛反应，生成6-芳基化菲啶。反应是通过将酰基基团加到异腈官能团上，以及随后的中间体亚氨基基团的分子内BHAS发生的。自由基链反应的引发最好用少量的FeCl 3（0.4 mol％）来实现，并且使用市售的廉价t BuOOH作为氧化剂。

  An acyl radical generation and functionalization strategy through direct photoexcitation of benzothiazolines has been developed. The formed acyl radical species can either be trapped by quinoxalin-2-ones to realize their C(3)-H functionalization or trigger a cascade radical cyclization with isonitriles to synthesise biologically important phenanthridines. The synthetic value of this protocol can be

  已经开发出通过苯并噻唑啉直接光激发的酰基自由基生成和功能化策略。形成的酰基自由基物质可以被喹喔啉-2-酮捕获以实现其C(3)-H官能化，或者引发与异腈的级联自由基环化以合成具有生物学重要意义的菲啶。该方案的合成价值可以通过含有重要天然产物和基于药物的复杂分子的喹喔啉-2-酮的修饰来进一步说明。
