Umpolung Synthesis of Pyridyl Ethers by BiV‐Mediated O‐Arylation of Pyridones
Angewandte Chemie, 2022 We report that O‐selective arylation of 2‐ and 4‐pyridones with arylboronic acids is affected by a modular, bismacycle‐based system. The utility of this umpolung approach to pyridyl ethers, which is complementary to conventional methods based on SNAr or ...

Streamlining the Synthesis of Pyridones through Oxidative Amination of Cyclopentenones [PDF]
Angewandte ChemieHerein we report the development of an oxidative amination process for the streamlined synthesis of pyridones from cyclopentenones. Cyclopentenone building blocks can undergo in situ silyl enol ether formation, followed by the introduction of a nitrogen ...
