Synthesis of thieno[2,3- c ]acridine and furo[2,3- c ]acridine derivatives via an iodocyclization reaction and their fluorescence properties and DFT mechanistic studies

In this paper, we report the novel synthesis of thieno[2,3- c ]acridine and furo[2,3- c ]acridine derivatives via an intramolecular iodocyclization reaction. The thieno[2,3- c ]acridine derivatives exhibited blue fluorescence in hexane. DFT and time-dependent (TD) DFT studies were carried out. This methodology provided a novel pathway to access thieno[2,3- c ]acridine and furo[2,3- c ]acridine derivatives via a 6- endo iodocyclization reaction.
