METHOD FOR THE USE OF 11CCARBON MONOXIDE IN LABELING SYNTHESIS OF 11C-LABELLED ESTERS AND ACIDS BY SENSITIZED 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 alcohols or water treated by photosensitizers are provided. The resultant carbon-isotope labeled esters and acids, 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.
