Palladium-Catalyzed C-H Arylation of Quinoidal Scaffolds Through Homogeneous and Heterogeneous Pathways: Advancing Toward Trypanocidal Prototypes.

A Pd-mediated C-H activation methodology was developed for the direct arylation of quinoidal skeletons, both by means of homogeneous catalysis and heterogeneous catalysis using metal-decorated carbon nanotubes, enabling the direct functionalization of quinones in moderate to excellent yields. The derivatives obtained were tested against trypomastigote forms of Trypanosoma cruzi, showing promising biological activity.
