We report the synthesis and evaluation of an enantiomerically enriched bifunctional chelator, (S)-C-NE3TA. The bifunctional chelator was efficiently prepared by regioselective and stereoselective ring opening of an aziridinium ion. The new chiral chelator instantly and almost completely bound to 64Cu at room temperature. The corresponding 64Cu-radiolabeled complex remained intact in human serum for
