A New Method for Radiosynthesis of (11)C-Labeled Carbamate Groups and its Application for a Highly Efficient Synthesis of the Kappa-Opioid Receptor Tracer [(11)C]GR103545

(11)C-labeled carbamates can be obtained in a three-component coupling reaction of primary or secondary amines with CO(2) and (11)C-methylation reagents. [(11)C]Methyl-triflate mediated methylation of carbamino adducts provides the corresponding (11)C-labeled carbamate groups in excellent yields und...

Sumario:(11)C-labeled carbamates can be obtained in a three-component coupling reaction of primary or secondary amines with CO(2) and (11)C-methylation reagents. [(11)C]Methyl-triflate mediated methylation of carbamino adducts provides the corresponding (11)C-labeled carbamate groups in excellent yields under mild conditions (temperatures ≤ 40°C, 2 min reaction time). The utility of the method has been demonstrated by a highly efficient radiosynthesis of [(11)C]GR103545.
