Copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) click chemistry has inherent challenges for copper-labeled radiopharmaceuticals. An azide-modified phosphonate-based cross-bridged macrocyclic chelator was synthesized for click chemistry conjuga

Ethylene cross-bridged tetraamine macrocycles are useful chelators in coordination, catalytic, medicinal, and radiopharmaceutical chemistry. Springborg and co-workers developed trimethylene cross-bridged analogues, although their pendant-armed deriva

The tricyclic bisamidines L1 and L2 are designed to be preconstrained so as to present synperiplanar donor sites for metal coordination. Their very different bite angles of 35° and 70° result from the incorporation of two five-membered instead of s

Dimethyl cross-bridged cyclam (DMCBCy) forms a very reducing CuI complex that possesses the highest known catalytic activity to date in atom transfer radical polymerization (ATRP) reactions. The value of the ATRP equilibrium constant in a reaction wi

The kinetic inertness of copper(II) complexes of several carboxymethyl-armed cyclams and cyclens in 5 M HCl have been determined confirming that the complex derived from cross-bridged cyclam (Cu-CB-TE2A) is by far the most resistant to acid decomplex

The cross-bridged tetraamine ligand 4,11-bis(carboxymethyl)-1,4,8,11-tetraazabicyclo[6.6.2]hexadecane (H2CB-TE2A) allows formation of a radio-copper complex with higher in vivo stability than that of the corresponding non-cross-bridged analog 1,4,8,1

The use of copper radioisotopes in imaging and therapy has prompted an increased interest in chelators which form stable copper complexes, such as Cu(II)-azamacrocyclic complexes. The effects of charge, stability and the size of the macrocyclic backb

Copper(II) and zinc(II) complexes of cross-bridged cyclam and cyclen with primary amide pendant arms (ligands 1 and 2) have been prepared and structurally characterized. The copper complex of cyclam-derived 1 has a Jahn–Teller distorted Cu(II) octa
