Abstract
Molecules labelled with the unnatural isotope fluorine-18 are used for positron emission tomography. Currently, this molecular imaging technology is not exploited at its full potential because many 18F-labelled probes are inaccessible or notoriously difficult to produce. Typical challenges associated with 18F radiochemistry are the short half-life of 18F (<2 h), the use of sub-stoichiometric amounts of 18F, relative to the precursor and other reagents, as well as the limited availability of parent 18F sources of suitable reactivity ([18F]F– and [18F]F2). There is a high-priority demand for general methods allowing access to [18F]CF3-substituted molecules for application in pharmaceutical discovery programmes. We report the development of a process for the late-stage [18F]trifluoromethylation of (hetero)arenes from [18F]fluoride using commercially available reagents and (hetero)aryl iodides. This [18F]CuCF3–based protocol benefits from a large substrate scope and is characterized by its operational simplicity.
