Asymmetric Synthesis of Chiral‐at‐P Alkenylphosphonamidates through Nickel‐Catalyzed C−P Coupling of Phosphoramidites and Alkenyl Halides

Abstract

AbstractP‐stereogenic compounds are widely used as ligands in asymmetric catalysis and are present in a myriad of bioactive compounds and pharmaceuticals. Yet, their stereocontrolled preparation remains challenging. Herein, we report a novel strategy towards versatile chiral‐at‐P alkenylphosphonamidates through a one‐pot Ni‐catalyzed C−P coupling/diastereoselective hydrolysis of readily available phosphoramidites and alkenyl halides. Remarkably, a chemo‐ and diastereodivergent behavior was observed upon subtle changes in the reaction conditions. Additionally, selective derivatizations of chiral alkenylphosphonamidates demonstrate their versatility as building blocks for the synthesis of structurally diverse P‐stereogenic compounds.
