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.

Novel and flexible routes for the synthesis of chiral ring annulet 2,6-disubstituted 1,4,7-trimethyl-1,4,7-triazamacrocycles are described. Efficient macrocyclisations were realised provided that chiral analogues of N,N-bis-[2-(toluene-sulfonylamino)ethyl]-toluene-4-sulfonamide were used as the nucleophilic components. Complexes prepared, in situ, from these 2,6-disubstituted 1,4,7-trimethyl-1,4,7-triazamacrocycles

[GRAPHICS]Novel chiral peraza-macrocycles were synthesized from chiral aziridines as a common building block. Efficient syntheses of chiral [26]-N-6, [12]-N-4, [9]-N-3, and [14]-N-4 systems were accomplished.
