Synthesis and Application of 1-[18F]Fluoro-4-isothiocyanatobenzene for Radiofluorination of Peptides in Aqueous Medium.

Journal of Organic Chemistry
Conjugation of radiofluorinated prosthetic groups to primary amines of peptides in an aqueous medium is still considerably challenging. Herein, we report a one-pot cascade synthesis of 1-[18F]fluoro-4-isothiocyanatobenzene ([18F]2d), an isothiocyanate ...

Synthesis of Dibenzothiophenium Salts and Observations in Radiofluorination

Synlett : Accounts and Rapid Communications in Synthetic Organic Chemistry
We demonstrate an alternative synthesis of dibenzothiophenium (DBT) salts through a three-step Pd-catalyzed arylation, oxidation, and cyclization sequence.

Radiofluorination of 2-Arylquinolin-4-yl Oxypropanamide Derivatives for TSPO Imaging in Neuroinflammatory Murine, Nonhuman Primates, and Human Brain Autoradiography with Insensitivity to the rs6971 Polymorphism.

Journal of Medicinal Chemistry
The 18 kDa translocator protein (TSPO) is a critical target for PET imaging of neuroinflammation in central nervous system (CNS) disorders; however, many clinical TSPO PET tracers are limited by sensitivity to rs6971 polymorphism.
