The inverse electron-demand Diels-Alder reaction as a new methodology for the synthesis of 225Ac-labelled radioimmunoconjugates

Chem Commun (Camb). 2018 Mar 8;54(21):2599-2602. doi: 10.1039/c7cc09129j.

Abstract

The inverse electron-demand Diels-Alder reaction between tetrazine (Tz) and trans-cyclooctene (TCO) facilitates the efficient radiosynthesis of 225Ac-labelled radioimmunoconjugates in a two-step method, outperforming conventional approaches based on isothiocyanate couplings.
