Described herein is the development of an iridium-catalyzed direct C-H amination of benzamides with anilines at room temperature, representing a unique example of an Ir catalyst system that is compatible with external oxidants. Mechanistic details, such as the isolation and characterization of key iridacycle intermediates, are also discussed.

activity against multidrug-resistant (MDR) and extensively drug-resistant (XDR) M. tb strains. It is worth noting that the two most active compounds 13c and 13d also exhibited the highest selective activity towards DS, MDR and XDR M. tb strains over mammalian cells [IC50 (Vero cells) ≥ 227 μM], indicating their potential lack of cytotoxicity. The four compounds were docked into the MmpL3 active site and
