model 11 C-carbonyl-labeled carbamates as well as symmetrical and unsymmetrical ureas based on their widespread use in radiotracer design and our clinical research interests for proof of concept. Utility of this method is demonstrated by the synthesis of a reversible radiopharmaceutical for monoamine oxidase B, [11 C]SL25.1188, and 2 novelfattyacidamidehydrolaseinhibitors. These radiotracers were
