Abstract: Eight symmetrical and asymmetrical dibenzo hydroxy crown ethers were synthesized via the reaction of 1, 1'-(o-phenyl enedioxy)bis(2, 3-epoxyprop) ether with catechol and alkyl substituted catechol (for example, 3,5-ditert-butyl catechol and saturated urushiol) in good yields, and their cis-trans isomers were easily separated by column chromatography and crystallization. The structure of the new compounds were determined by IR, 1H NMR, MS, elementary analysis.
Key words: Hydroxy crown, Cis-trans isomers, Thin-layer chromatography
