Abstract

In this research, due to the high importance of Crown Ethers in complexometric and also in the field of pharmacology, a new method for the preparation of several heterocyclic crowns ethers was proposed using titanium nano-oxide catalysts. To this end, the reaction of 2-methyl-Indole with tosylated triethylene glycol, led to the formation of 2-methyl-1-(2-(2-(2-(2-methyl-H1-1-Indole (ethoxy) (ethoxy) ethyl)-1H-Indole in DMF solvent and the KOH. After determining the optimum conditions for the preparation of the crowns (room temperature, dichloromethane solvent and the catalytic ratio of 5 mol%), the chronological derivatives of the Crown Ethers were obtained from the reaction of the 2-methyl-1-(2-(2-(2-(2-methyl-H1-1-Indole (ethoxy) (ethoxy) ethyl)-1H-Indole with different derivatives of aldehydes. One of the advantages of this method is the high efficiency, non-toxicity of the catalyst, and its reuse.
