Synthesis and self-assembly properties of a glycyrrhetinic acid conjugate containing uracil and 2,6-diaminopyridine units

A novel glycyrrhetinic acid conjugate containing uracil and 2,6-diaminopyridine units was synthesized and the exclusive supramolecular dimeric structure through six intermolecular hydrogen bonds was characterized by NMR spectroscopy and ESI-MS. The supramolecular dimeric structure could recognize the polar molecule in aprotic polar solvents.
