Abstract
![]()
The development of
very fast, clean, and selective methods for
indirect labeling in PET tracer synthesis is an ongoing challenge.
Here we present the development of an ultrafast photoclick method
for the synthesis of short-lived 18F-PET tracers based
on the photocycloaddition reaction of 9,10-phenanthrenequinones
with electron-rich alkenes. The respective precursors are synthetically
easily accessible and can be functionalized with various target groups.
Using a flow photo-microreactor, the photoclick reaction can be performed
in 60 s, and clinically relevant tracers for prostate cancer and bacterial
infection imaging were prepared to demonstrate practicality of the
method.
