• Selective Synthesis of Dihydrophenanthridine and Phenanthridine Derivatives from the Cascade Reactions of <i>o</i>-Arylanilines with Alkynoates through C–H/N–H/C–C Bond Cleavage

  unprecedented selective synthesis of dihydrophenanthridine and phenanthridine derivatives through the cascade reactions of 2-arylanilines with alkynoates is presented. Mechanistic studies showed that the formation of the dihydrophenanthridine scaffold involves an initial C(sp2)–H alkenylation of 2-arylaniline with alkynoate followed by an intramolecular aza-Michael addition. When this reaction is carried out

  在本文中，提出了通过2-芳基苯胺与链烷酸酯的级联反应对二氢菲啶和菲啶衍生物进行空前的选择性合成。机理研究表明，二氢菲啶骨架的形成涉及初始C（sp 2）–炔基酸将2-芳基苯胺的H烯基化，然后进行分子内氮杂-Michael加成反应。当该反应在高温下进行时，原位形成的取代的二氢菲啶很容易发生逆曼尼希型反应，通过CC键断裂得到相应的菲啶。与文献方法相比，该新颖方案具有诸如容易获得的具有游离氨基的底物，药学上特权的产品，廉价的催化剂以及方便地可控制的选择性的优点。

  AbstractThe di‐tert butyl peroxide (DTBP)‐promoted sequential reaction of isonitriles is developed, leading to 6‐methylphenanthridine derivatives in moderate to excellent yields. DTBP served as both promoter and methyl source. The procedure proceeds through the addition of a methyl radical derived from the peroxide to the isonitrile followed by aromatic homolytic cyclization. It tolerates a series of functional groups, such as fluoro, chloro, acetyl, methoxycarbonyl, cyano and trifluoromethyl.magnified image
• Metal-Free Nitrogenation of 2-Acetylbiphenyls: Expeditious Synthesis of Phenanthridines
  作者：Conghui Tang、Yizhi Yuan、Ning Jiao

  DOI：10.1021/acs.orglett.5b00797

  日期：2015.5.1

  An intermolecular nitrogenation reaction toward the synthesis of phenanthridines has been developed. This metal-free protocol provides a novel nitrogen-incorporation transformation using azides as the nitrogen source. Phenanthridines, which are of great interest in pharmaceutical and medicinal chemistry, are synthesized efficiently in one step. Moreover, the byproducts derived from the Schmidt reaction are inhibited, which further demonstrated the high chemoselectivity of this transformation.
