[reaction: see text] A one-pot, t-BuLi-induced synthesis of 6-substitutedphenanthridines from fluoroarenes and nitriles via 1,2-arynes is reported. Aryl- and hetaryl nitriles, cyanamides, and trimethylacetonitrile gave phenanthridineproducts. The method was extended to provide bisphenanthridine 10 by a one-pot bis-cyclization, using 1,3-dicyanobenzene and PhF in 1:5 ratio. Reaction of 1-fluoronaphthalene

An efficient functional group induced strategy for the synthesis of 6-aminophenanthridines (6AP) has been developed as a result of an in situ generated novel system “CO–CH(N1N2)”. This reaction presents a new mode of N2 extrusion in benzotriazoles that later result in decarbonylative cyclization to 6AP. This method offers an easier protocol for the synthesis of 6AP from readily available inexpensive
由于原位产生的新型系统“ CO-CH(N 1 N 2)”的结果,已开发出一种有效的官能团诱导的6-氨基菲啶(6AP)合成策略。该反应提供了在苯并三唑中N 2挤出的新模式,该新模式随后导致脱羰基环化为6AP。该方法为从容易获得的廉价底物合成6AP提供了更简单的方案。
