Graphical Abstract:


Novel spiro bis-crown ethers derivatives with four benzo units connected via one carbon bridges have been prepared. These compounds represent well preorganized cavities with interesting complexation abilities towards cations. These macrocyclic were prepared by a four-step via template method by utilizing simple precursors catechol, oliethylen glycol and penta erythritol tetra bromide in good yield. Additionally, cesium carbonate could be used as an excellent base for these reactions.

Keywords: Bis crown ether; bis phenol; cesium carbonate; mix donor; spiro; penta erythritol tetra bromide.
