Method for the use of 11C carbon monoxide in labeling synthesis of 11C-labelled ketones by photo-induced free radical carbonylation

摘要

Methods and reagents for photo-initiated carbonylation with carbon-isotope labeled carbon monoxide using alkyl/aryl iodides with carbanion precursors pretreated by a base are provided. The resultant carbon-isotope labeled ketones, and pharmaceutical acceptable salts and solvates are useful as radiopharmaceuticals, especially for use in Positron Emission Tomography (PET). Associated kits and method for PET studies are also provided.
