Synthesis of alkyl- and poly(ethylene)glycol linked bis-dioxocyclams from bis-chromium carbene complexes
… reaction to form 14-membered bis-imine bis-dioxocyclams. Unfortunately, all attempts to reduce the imine-cyclams to give the stable dioxocyclams were unsuccessful. Both tri- and tetra(ethylene glycol) linked bis-chromium carbene complexes have been synthesized. These carbene complexes were …

Synthesis of unsymmetrical pendant-armed and phosphonic acid-pendant-armed cross-bridged tetraazamacrocycles
… unsymmetrical pendant-armed cross-bridged cyclams.*.</p><p>Attempts were made toward the synthesis of two potential bifunctional chelators for radiopharmaceuticals, each bearing only one phosphonic acid pendant arm and one free carboxylate for conjugation to somatostatin analogues.*.</p>

Studies on the Phospho-Aldol Reaction Catalysed by Aluminium Salcyan and Related Complexes
… One such area focuses on the incorporation of cyclams into the salcyen backbone, which could serve as a versatile framework for PA catalysts with the inclusion of a secondary basic functionality. The second area introduces phosphine oxide and phosphine substituted N2O2 salcyan compounds, which …

Synthese und Charakterisierung Cyclam-basierter Multimere als Basis für Radiopharmaka
… Daher wurden die Aminstickstoffatome des Cyclams direkt geschützt. Ausgehend von Cyclam-Boc3 konnten über Kupplungsreaktionen Aminosäure- und Dipeptidmethylester als unsymmetrische Cyclamderivate gewonnen werden. Damit ist ein Syntheseweg entwickelt worden, der die Darstellung …

The synthesis of biologically active oxa-polyamine analogues, homologues and conjugates.
… (bis-benzylspermine), and anti-HIV activities (cyclams). Recent studies have shown that oxa-polyamines such as 3-aminooxy-1-aminopropane (APA) and others form an interesting group of compounds exhibiting a number of biological activities. The presence of an oxygen atom next to a nitrogen atom …
