A new simple and convenient method for the synthesis of macrocyclic polyether-diester compounds containing pyridine and phenyl subcyclic units is developed. Various diacids, are selectively esterified in excellent yields by reaction with oligoethylene glycols in the presence of Al2O3/MeSO3H (AMA) as a new reagent without use of any solvents.

Several macrocyclic di- or tetraester/ether compounds were readily prepared by reacting various oligoethylene glycols with aliphatic and aromatic diacid chlorides, and hetero atoms-containing diethylene glycols with adipoyl chloride by the use of dibutyltin oxide in good yields.
