  Expeditious Synthesis of Phenanthridines from Benzylamines via Dual Palladium Catalysis

  摘要：

  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.

  syntheses of both the benzo[b]phenanthridine and the 6H-dibenzo[c,h]chromen-6-one motif are described. Reaction of (2-(3-bromo-1,4-dimethoxynaphthalen-2-yl)phenyl)methanamine with PIFA afforded benzo[b]phenanthridine-7,12-dione, while the related nonbrominated precursor, (2-(1,4,5-trimethoxynaphthalen-2-yl)phenyl)methanamine on treatment with PIFA, furnished the ortho-quinone 1-methoxybenzo[c]phenanthridine-11

  描述了苯并[ b ]菲啶和6 H-二苯并[ c，h ] chromen-6-一个基序的新颖合成。（2-（3-溴-1,4-二甲氧基萘-2-基）苯基）甲胺与PIFA的反应制得苯并[ b ]菲啶-7,12-二酮，而相关的非溴化前体是（2-（1，用PIFA处理4,5-三甲氧基萘-2-基）苯基）甲胺，得到邻-醌-1-甲氧基苯并[ c ]菲啶-11,12-二酮。出乎意料的是，在O 2气氛下用NBS处理相关的氧类似物，例如（2-（1,4-二甲氧基萘-2-基）苯基）甲醇，得到色酮12-甲氧基-6 H-二苯并[ c，h]] chromen-6-one。
