The atroposelective synthesis of PINAP ligands has been accomplished via a palladium‐catalyzed C−P coupling process through dynamic kinetic asymmetric transformation. These catalytic conditions allow access to a wide variety of alkoxy‐ and benzyloxy‐substituted PINAP ligands in high enantiomeric excess. The methods described in this communication afford valuable P,N ligands in good yields and high

A dynamic kinetic asymmetric transformation (DYKAT) technique has been designed for the synthesis of 2'-substituted 2-aryl pyridines/isoquinolines and related heterobiaryls. In this way, the Pd(0)-catalyzed coupling of racemic 2-triflates with aryl boroxines using a TADDOL-derived phosphoramidite as the ligand provides the corresponding coupling products with good to excellent enantioselectivities
