On the synthesis of unsymmetrical bis(macrocyclic) ligands
摘要:
The syntheses of novel three and four carbon-bridged unsymmetrical bis(macrocyclic) ligands have been investigated. Suitable functionalization of a selectively protected 1,4,7-triazacyclononane macrocycle allows for the coupling of this well-studied ligand to either 1,4-diazacyclononane or 4,7-diaza-1-oxacyclononane.
