Silver-promoted (radio)fluorination of unsaturated carbamates via a radical process

Abstract

The intramolecular fluorocyclization of unsaturated carbamates proceeds <italic>via</italic> a cyclization/1,2-(hetero)aryl migration/fluorination cascade involving an unusual radical process, and provides a straightforward access to (radio)fluorinated oxazolidin-2-ones, oxazolidine-2,4-diones and 1,3-oxazinan-2-ones.
