The discovery and development of a general method for the one-pot synthesis of substituted phenanthridines 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 been obtained in good yields.

A metal-free radical oxidative decarboxylation/cyclization of acyl peroxides and 2-isocyanobiphenyls was achieved, leading to 6-aryl phenanthridines as well as 6-alkyl phenanthridines in moderate to good yields. The procedure featured simple conditions and was metal-free and base free. It represents a practical approach to access 6-aryl/alkyl phenanthridines.
Arylative cyclization of 2-isocyanobiphenyls with anilines: One-pot synthesis of 6-arylphenanthridines via competitive reaction pathways
Xia, Zhonghua,Huang, Jinbo,He, Yimiao,Zhao, Jiaji,Lei, Jian,Zhu, Qiang
, p. 2546 - 2549 (2014/05/20)
A transition-metal-free method for the synthesis of C6 phenanthridine derivatives by arylative cyclization of 2-isocyanobiphenyls with arylamines in one pot was developed. Mechanistic studies suggest that electrophilic aromatic substitution (SEAr) of a nitrilium intermediate and homolytic aromatic substitution (HAS) of an imidoyl radical intermediate are two competitive reaction pathways involved in the annulation step.
Synthesis of phenanthridine derivatives via cascade annulation of diaryliodonium salts and nitriles

A cascade coupling reaction toward a variety of phenanthridine derivatives has been developed. This cascade transformation proceeds via the copper-catalyzed coupling reaction of diaryliodonium salts and nitriles, and undergoes cyclization into the phenanthridine core.

6-Aryl substituted phenanthridines were synthesized via a visible-light-catalyzed cyclization of 2-isocyanobiphenyls with arylsulfonyl chlorides under oxidant-free and transition-metal-free conditions. This transformation represents an efficient and attractive synthetic utilization of arylsulfonyl chlorides. the Partner Organisations 2014.
