The synthesis of unsymmetrically N-substituted chiral 1,4,7-triazacyclononanes

Author affiliations

Abstract

A number of chiral unsymmetrically N-substituted 1,4,7-triazacyclononane ligands have been prepared by modular methods. The key step in the synthesis centres on the macrocyclisation of three tertiary amide precursors under standard Richman–Atkins conditions which allows for subsequent N-functionalisation.
