Abstract
A one-pot umpolung method for the ring-opening pyridylation of unstrained cyclic amines was developed using N-amidopyridinium salts. This process involves the formation of electron donor-acceptor complexes between bromide and N-amidopyridinium salts, ultimately leading to the functionalization of pyridines. This protocol is compatible with a range of 5- or 6-membered cyclic amines and pyridines, thereby providing a powerful synthon for preparing C4-functionalized pyridines under visible-light conditions in the absence of an external photocatalyst. © 2023 American Chemical Society
