Expedient Access to 18F-Fluoroheteroarenes via Deaminative Radiofluorination of Aniline-Derived Pyridinium Salts.

open access: yesAngewandte Chemie International Edition, Volume 63, Issue 26, June 21, 2024.
Herein, we disclose that pyridinium salts derived from abundant (hetero)anilines represent a novel precursor class for nucleophilic aromatic substitution reactions with [18F]fluoride.

Expedient Access to 18F‐Fluoroheteroarenes via Deaminative Radiofluorination of Aniline‐Derived Pyridinium Salts [PDF]

open access: hybridAngewandte Chemie, Volume 136, Issue 26, June 21, 2024.
18F‐Fluoroheteroarenes find wide application as radiotracers for PET (positron emission tomography) imaging. Here, we present a deaminative radiosynthetic approach via pyridinium tetrafluoroborates that facilitates radiofluorination of 33 structurally diverse heteroarenes in up to 98 % RCY (radiochemical yield).

Preparation and Preclinical Evaluation of 18F-Labeled Olutasidenib Derivatives for Non-Invasive Detection of Mutated Isocitrate Dehydrogenase 1 (mIDH1) [PDF]

open access: yesMolecules
Mutations of isocitrate dehydrogenase 1 (IDH1) are key biomarkers for glioma classification, but current methods for detection of mutated IDH1 (mIDH1) require invasive tissue sampling and cannot be used for longitudinal studies.

Phosphonate-Based Aza-Macrocycle Ligands for Low-Temperature, Stable Chelation of Medicinally Relevant Rare Earth Radiometals and Radiofluorination. [PDF]

open access: yesJ Am Chem Soc
Radioisotopes of fluorine (18F), scandium (43/44Sc, 47Sc), lutetium (177Lu), and yttrium (86Y, 90Y) have decay properties ideally suited for targeted nuclear imaging and therapy with small biologics, such as peptides and antibody fragments.
