Beyond azide-alkyne click reaction: easy access to 18F-labelled compounds via nitrile oxide cycloadditions

Chem Commun (Camb). 2012 Jul 21;48(57):7134-6. doi: 10.1039/c2cc31335a. Epub 2012 Apr 25.

Abstract

Radiofluorinated 4-fluorobenzonitrile oxide and N-hydroxy-4-fluorobenzimidoyl chloride rapidly react with different alkenes and alkynes under mild conditions. These cycloadditions are suitable for the preparation of low-molecular weight radiopharmaceuticals and, in a strain-promoted variant, can enable easy labelling of sensitive biopolymers.
