This work presents the synthesis and characterization of L2 and L3, which formed with the previously described ligand L1 a family of three tris(tetraamine) ligands based on a mesitylenyl spacer, The trimeric ligands differ from one to the other by the nat

The reaction of cyclen 1 with chloral hydrate afforded exclusively 1,4,7-triformylcyclen 2 in high yield; the triprotected macrocycle was easily alkylated with various electrophiles in good to excellent yields. The alkaline removal of the formyl groups pr
