radioactivities, necessitating their radiosynthesesfrom cyclotron-produced no-carrier-added [18F]fluorideion. PET radiotracers encompass wide structural diversity and molecular weight. Hence, diverse 18F-labeling methodology is needed to accomplish the required radiosyntheses in a simple and rapid manner. A useful strategy is to introduce nucleophilic [18F]fluorideion first into a labeling synthon that
Fast and reliable method for the preparation of ortho- and para-[18F]fluorobenzyl halide derivatives: Key intermediates for the preparation of no-carrier-added PET aromatic radiopharmaceuticals
Reduction of the aldehydes (>95%) was near-quantitative with an aqueoussolution of NaBH4. Halogenation was performed on the same support with different aqueoussolutions of concentrated acid (HI, HBr, HCl). The conversion of benzyl alcohols into [18F]fluorobenzyl halides (X = Cl, Br, I) usually proceeded within 2 min at high yields. The halogenation proceeded at room temperature, with the exception of the
