chemistry. Here we report the first C–H pyridonation of unactivated (hetero-)arenes, providing a methodology to directly access N-aryl-2- and 4-pyridones. Generation of pyridinium radical cations through single-electronreduction allows for the synthesis of pyridones on structurally complex molecules.
The present invention provides compounds and compositions thereof which are useful as inhibitors of plasma kallikrein and which exhibit desirable characteristics for the same.
