The diesters 3 and 4 prepared by o-alkylations of 1,1'-bi-2-naphthol and 2,
2'-dihydroxybiphenyl with ethyl chloroacetate and the 1,3-diester of calix[
4]arene undergo aminolysis with diethylenetriamine and 3,3'-diaminodipropyl
amine to provide dioxadiamide-amine based macrocycles. Amongst these macroc
ycles calix[4]arene based macrocycle 10 shows moderate selectivity towards
Pb2+ over alkali and alkaline earth metal cations.
