accelerate the macrocyclization process but also have a great impact on the distribution of macrocyclicproducts in the presented libraries, promoting the formation of macrocyclic compounds and eliminating the linear ones. The distribution of macrocyclicproducts was also found to be strongly dependent on the structural features of the substrates employed. Furthermore, in three- and four-substrate CLs we

improvement of our own method for synthesising macrocyclic compounds via doubleamidation reactions of aromatic dimethyl esters with five oxa-aliphatic α,ω-diamines of different lengths, leading to a large library of potential ion receptors. We studied the influence of various inorganic salts (NaCl, KCl, CsCl, NH4Cl, MgSO4, CaCl2, CuSO4) on the macrocyclization reaction. The results were analyzed in terms of
