The NET-targeted radiotracers [18F]4F-mHPG and [18F]3F-pHPG have demonstrated promising clinical applications; however, the preparation of these tracers remains challenging. Herein, we report an improved synthesis protocol that enables the efficient automated production of two PET tracers via photocatalyzed 18F-deoxyfluorination. [18F]4F-mHPG and [18F]3F-pHPG were prepared in excellent n.d.c. RCYs of 31.3 ± 0.4% and 22.4 ± 1% in only 1 h from readily available precursors, and further validated on the PC12 tumor model for head-to-head comparison.
