      Abstract: Some new oxygen-sulfur, multibenzo   macrocyclic ligands containing amide groups have been prepared   using the macrocyclization process with the reaction of   2,2'-thiobis-[4-methyl(2-aminophenoxy)phenyl ether] as a   symmetrical diamine with appropriate dicarboxylicacid dichlorides   in moderate yields. This macrocyclization led to the formation of   di- and tetramide macrocycles. These reactions were routinely   carried out at ambient temperature in CH2Cl2 as solvent in high   dilution without template effect conditions. It is found that   sulfur the atom affects the rigidity of the macrocycles and   diastereotopicity of nuclei in the ring of these series of   macrocyclic compounds.
