synthesis of Palomid 529, a drug in development for the treatment of glioblastoma and neovascular age-related macular degeneration. With a combination of experimental and theoretical methods, we get more insight into the essential issues of strategy determining the reaction process. The stronger coordinating ability of 2-aryloxypyridine and the less steric hindrance of amide are pivotal to the high chemoselectivity

oxidative C−H/C−H cross‐coupling reaction between an N‐acylaniline and a benzamide has been accomplished for the first time. This process constitutes a step‐economic and highly efficient pathway to 2‐amino‐2′‐carboxybiaryl scaffolds from readily available substrates. A Cp*‐free RhCl3/TFA catalytic system was developed to replace the [Cp*RhCl2]2/AgSbF6 system generally used in oxidative C−H/C−H cross‐coupling
