Abstract

Macrocyclic compounds with pendant-arms are designed with two principal aims: modification of the coordinating properties of the parent ligand, and introduction of the ancillary groups in order to provide a specific application in a particular area of scientific research such as bioinorganic chemistry [1], anionic receptors [2], contrast agents in medicine [3], and so forth.The synthesis of a new trans-substituted organic ligand with methylpyridine groups stemming from a precursor with secondary amines, allows to optimize its ability to coordinate to transition metals and lanthanide ions [4].
