Newly designed small and hydrophilic clickreaction devices, NMs-4,8-diazacyclononynes (NMs-DACNs), have been efficiently synthesized by a one-pot double Nicholas approach. NMs-DACNs react with azi...
the limited cell permeability and chemical tractability of such agents remain to be addressed. We envisioned that target-templated synthesis of such mid-sized molecules might provide a solution. Here, we exploited a copper-free Huisgen cycloaddition for template synthesis using a peptide fragment containing a 4,8-diazacyclononyne (DACN) moiety and an azide-containing fusicoccin derivative in the presence
