A novel functionality was introduced in the pillararene family by the Claisen rearrangement of monoallyl pillararene. This new key derivative can lead to the formation of a 10 + 1 functionalized derivative, a useful scaffold for further derivatization. Except for the previously known monodeprotection reaction, all steps proceed efficiently with high yields and easy separation. In addition, a solvent-responsive pseudorotaxane was synthesized based on this novel functionality.
