Treating derivatives of m-phenylenediamine having different electron-richness and reactivities with triphosgene in the presence of triethylamine led to aromatic tetraurea macrocycles in high yields. Factors important for efficiently forming these macrocycles include the molar ratio (2:1) between the diamine and triphosgene, reaction temperature (-75 °C), and solvent (CH2Cl2). By controlling the order and rate for adding diamines, tetraurea macrocycles consisting of two different types of monomeric residues have also been obtained in high yields.
A click chemistry approach for the synthesis of macrocycles from aryl amide-based precursors directed by hydrogen bonding

experimental part, p. 3243 - 3250 (2009/10/24)
This paper describes the synthesis of four aryl amide-based macrocycles through the 1 + 1 formation of two 1,2,3-triazole units by click chemistry. Two series of aryl amide-based precursors that bear two azide or acetylene units have been prepared. Intram

Ortho-nitro- and ortho-alkoxy-oligo-meta-aniline units fold in solution through hydrogen bonds and aromatic stacking into compact structures that were characterized in the solid state as cylindrical β-sheet like structures.
