Structure and properties of novel oxa-aza macrocycles derived from dialdehydes and diamines

Over the last couple of decades the oxa-aza macrocycles have been extensively studied due to possible application as selective separating agents for toxic metal cations, chemical sensors and other application. The affinity of macrocyclic system for metal cation can be manipulated by several designable structural factors such as ; cavity size, conformation of donor atoms, flexibility of system, orientation of the potential donor atoms, torsion angles associated with these atoms, distances between donor atoms etc. There are several synthetic strategies for preparation of oxa-aza macrocycles, among them cyclocondenzation reaction of poly-amine and poly-aldehyde precursors resulting in a formation poly-imine compounds was found to be especially convenient. In our work we have developed relatively simple and efficient method for preparation of oxa-aza imine macrocycles by [1+1] and [2+2] cyclocondenzation reactions and efficient method for reduction of poly-imine macrocycles to poly-amine macrocycles. Crystal and molecular structures of prepared compounds were determined and the above mentioned structural factors were correlated with different properties such as metal ion extraction capabilities.
