A concise method for fully automated radiosyntheses of [18F]JNJ-46356479 and [18F]FITM via Cu-mediated 18F-fluorination of organoboranes†
Abstract
A modified alcohol-enhanced 18F-fluorodeboronation has been developed for the radiosyntheses of [18F]JNJ-46356479 and [18F]FITM. Unlike the [18F]KF/K222 approach, this method tolerates the presence of sensitive heterocycles in Bpin precursors 4 and 8 allowing a one-step 18F-fluorodeboronation on the fully automated TRACERlabâ„¢ FXFN platform.
