Two routes to the synthesis of a cyclohexyl-fused 1,4,7-triazacyclononane involving macrocyclisations of tosamides have been investigated. In the first approach, using a classic Richman-Atkins-type cyclisation of a cyclohexyl-substituted 1,4,7-tritosamide with ethylene glycol ditosylate, afforded the cyclohexyl-fused 1,4,7-triazacyclononane in 5.86% overall

Recently, a straightforward one-pot method for 18F-fluoroethylation without azeotropic drying of cyclotron-produced [18F]F- was developed. In this study, we have attempted to simplify the automated radiosynthesis of two [18F]fluoroethylated tracers, [18F]FEDAC and [18F]FET, using a desmethyl labeling precursor and [18F]fluoroethyl
Selective bridging of p-tert-butylcalix [6] arene with polyethylene glycol ditosylates.

Bis(Zn-dipicolylamine (Zn-DPA)) coordination complexes represent a new class of synthetic small molecules that can target anionic phosphatidylserine (PS) in the apoptotic cells with high affinity and specificity. In this study, we labeled Zn-DPA and Cy7-Zn-DPA with different (18)F-prosthetic groups and
