  铜催化无保护苯胺衍生物的有氧苄基 C(sp3)−H 氧化反应合成菲啶

  摘要：

  在此，我们报道了在有氧条件下铜催化未保护的苯胺衍生物的分子内苄基C(sp3)−H氧化，从而能够制备菲啶化合物。据我们所知，这是在 Cu/O2 体系下由未保护的苯胺形成脱氢 C(sp3)−N 键的开创性反应。值得注意的是，具有烷基、甲氧基、卤素（氟、氯、溴和碘）、三氟甲基、三氟甲氧基、氰基、酯和缩醛基团的各种苯胺也可以参与该反应。

  Where HAS you been? A manganese‐mediated annulation of 2‐isocyanobiaryls with organoboronic acids is developed for the synthesis of a broad range of phenanthridine derivatives (see scheme). Mechanistic studies indicate that the reaction proceeds by the intramolecular homolytic aromatic substitution (HAS) of an imidoyl radical intermediate.

  containing a pending isocyanide moiety under palladium catalysis, has been developed. This process involves sequential intermolecular isocyanide insertion to an aryl palladium(II) intermediate and intramolecular aromatic C–H activation as key steps. Alkyl palladium(II) intermediate lacking β-hydrogen is also applicable to this reaction, generating unique bisheterocyclic scaffolds with three C–C bonds being

  DOI：10.1021/ol102509n

  A method for the synthesis of phenanthridines from benzylamines and aryl iodides which uses a dual palladium-catalyzed process is developed. The domino sequence ends via an intramolecular amination and an oxidative dehydrogenation. No protecting group or prefunctionalization of the amine is required, and the process uses dioxygen as the terminal oxidant.
• Metal-free photocatalyzed cross coupling of aryl (heteroaryl) bromides with isonitriles

  日期：2017.12

  A visible-light-catalyzed synthesis of 6-aryl substituted phenanthridines from aryl bromides and 2-isocyanobiphenyls at room temperature has been discovered. This metal-free cross-coupling reaction offers rapid and sustainable access to a series of structurally complex and diverse phenanthridines. The usage of inexpensive Rhodamine 6G as the catalyst with easy operation makes this protocol very practical. (C) 2017 Elsevier Ltd. All rights reserved.
