Palladium-Catalyzed Site-Selective Benzocyclization of Naphthoic Acids with Diaryliodonium Salts: Efficient Access to Benzanthrones

Dual activation of both C-I and vicinal C-H bonds of diaryliodonium salts allowing for diarylation is a subject of rapid construction of π-extended frameworks. Here, we report palladium-catalyzed cascade of C8-arylation/intramolecular Friedel-Crafts acylation of α-naphthoic acids in the synthesis of benzanthrone derivatives. The step-economical protocol tolerates various substrates, which resulted in a potential molecular library for developing functional polycyclic scaffolds. The approach relies on the synergistic action of strong acid with palladium catalysts to form two bonds in a one-pot procedure.

Selective introducing of aryl and amino groups: Reaction of benzanthrone and organometallic reagents

The reaction of benzanthrone and aryl magnesium bromides produced 6-aryl-substituted benzanthrones in moderate to good yields. Similarly, 6-alkylaminobenzanthrones were selectively prepared by the reaction of benzanthrone and lithium alkylamides. In contrast, for the lithium arylamides, the arylamino groups were selectively introduced at the 4-position of the benzanthrone.
