The approach enables the incorporation of a peptidomimetic linker, significantly modulating the biological and cation complexation properties of the obtained compounds. All derivatives were obtained in crystalline form, allowing unambiguous structural elucidation by single-crystal X-ray diffraction, which revealed macrocyclic architectures stabilized by intramolecular hydrogen bonding.
Graniczny et al. (Sat,) studied this question.
