A rigid C-3v-symmetrical host molecule, syn-1,3,5-tris(2-hydroxy-5-pentylphenyl)-2,4,6-trimethylbenzene, was readily obtained via Suzuki coupling and thermal atropisomerization. The host molecule effectively associated with various saccharides by multipoint hydrogen bonds, whereas its anti-atropisomer and analogue lacking in methyl groups showed much weaker association with saccharides. Thermodynamic analyses suggested that the difference of the association strength was caused by entropic factors.

A concise access to C3-symmetric macrocyclic triimines was developed. When biphenyls having a formylgroup on one phenyl group and an NHBoc group on the other phenyl group were treated with an excess amount of concentrated HCl in 1,4-dioxane, the detachment of the Boc group followed by a trimerization reaction via imine formation proceeded smoothly to afford C3-symmetric imine-linked macrocycles in
