The invention provides a method for radiofluorination of biological vectors such as peptides comprising reaction of a compound of formula (II): or a salt thereof with a source of [
18
F]-fluoride, to give a compound of formula (I): or a salt thereof. The method may be effected under mild reaction conditions and offers a more chemoselective labelling approach Novel reagents for use in the radiofluoridation method, and uses of the resultant
18
F-labelled vectors are also provided

The invention relates to methods for processing [
18
F]-fluoride target water using a solid-support bound Cryptand of formula (I)
and to apparatus for performing such methods. The resultant [
18
F]-fluoride is useful for preparation of radiopharmaceuticals by nucleophilic fluorination, specifically for use in Positron Emission Tomography (PET).

[EN] The invention provides a method for radiofluorination of biological vectors such as peptides comprising reaction of a compound of formula (II): or a salt thereof with a source of [18F]-fluoride, to give a compound of formula (I): or a salt thereof. The method may be effected under mild reaction conditions and offers a more chemoselective labelling approach Novel reagents for use in the radiofluoridation method, and uses of the resultant 18F-labelled vectors are also provided [FR] L'invention propose un procédé pour la radiofluorination de vecteurs biologiques tels que des peptides, comportant la réaction d'un composé de formule (II) : ou d'un sel de celui-ci avec une source de [18F]-fluorure pour donner un composé de formule (I) : ou un sel de celui-ci. Le procédé peut être effectué dans des conditions réactionnelles douces et offre une approche de marquage qui est davantage chimiosélective. L'invention propose également de nouveaux réactifs destinés à être utilisés dans le procédé de radiofluorination ainsi que des utilisations des vecteurs obtenus par le marquage par 18F.
