A facilesynthesis of hydroxy cryptands by the reaction of diglycidyl ethers with a diazacrown ether is reported. The reaction results in a mixture of bi- and tri-cyclic cryptands which can be separated by chromatography. The yield of bicyclic cryptands is lowered with a decrease in the diazacrown ether cycle size and an increase in the number of oxyethylene moieties between the epoxy groups in the
