Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A new zwitterionic organotrifluoroborate is appended to three radiosynthons that afford undergo facile bioconjugation to several clinically relevant peptides and one enzyme inhibitor. Molecularly complex bioconjugates are ¹⁸F‐labeled in a single aqueous step in rapid time (&lt;15 min) without HPLC purification to afford tracers in good yields (&gt;200 mCi, 20–40 %) at high specific activity (≥3 Ci/μmol) and at &gt;98 % purity. PET imaging shows in vivo stability and tumor uptake.</p> </abstract>
