abstract = {The potential of many 18F-labeled (hetero)aromatics for
applications in positron emission tomography remains
underexplored because convenient procedures for their
radiosynthesis are lacking. Consequently, simple methods to
prepare radiofluorinated (hetero)arenes are highly sought
after. Herein, we report the beneficial effect of primary
and secondary alcohols on Cu-mediated 18F-labeling. This
observation contradicts the assumption that such alcohols
are inappropriate solvents for aromatic fluorination.
Therefore, we developed a protocol for rapid radiolabeling
of an extraordinarily broad scope of boronic and stannyl
substrates under general reaction conditions. Notably,
radiofluorinated indoles, phenols, and anilines were
synthesized directly from the corresponding unprotected
precursors. Furthermore, the novel method enabled the
preparation of radiofluorinated tryptophans, [18F]F-DPA,
[18F]DAA1106, 6-[18F]FDA, and 6-[18F]FDOPA},
