A series of new tweezers amido-amine ligands containing pyrrole, bipyrrole, and dipyrrolylmethane fragments were synthesized by reaction of 2-thioxothiazolidin-3-yl derivatives of alpha-pyrrolecarboxylic acids 5-[1(5-carboxy-3-methyl-4-phenyl-1H-pyrrol-2-yl)-methylethyl]-4-methyl-3-phenyl-1H-pyrrole-2-carboxylic acid, 5-[(5-carboxy-3-methyl-4-phenyl-1H-pyrrol-2-yl)phenylmethyl]-4-methyl-3-phenyl-1H-pyrrole-2-carboxylic acid, 5-(5-carboxy-3-methyl-4-phenyl-1H-pyrrol-2-yl)-4-methyl-3-phenyl-1H-pyrrole-2-carboxylic acid, and 3,4-dimethyl-pyrrole-2,5-dicarboxylic acid} with o-phenylenediamine. All compounds obtained were characterized by elemental analysis, NMR and mass spectra.
