The invention relates to precursors for the production of optically active 18 F-labelled amino acids bearing the radiochemical label on an aromatic ring, in particular 6-[ 18 F]Fluoro-3,4- dihydroxy-L-phenylalanine ([ 18 F]-L-DOPA) as well as meta- and para-[ 18 F]Fluoro-L- tyrosine. Further, it relates to a radiochemical method for the production of the corresponding radiotracers. |
