- Self-assembly of pseudo-rotaxane and rotaxane complexes using an electrostatic slippage approach
-
The protonation of a cyclic tertiary amine, integrated into the structure of a dumbbell-shaped guest molecule, accelerates the sliding of the guest through the cavity of a crown ether macrocycle to yield a stable pseudo-rotaxane complex. The use of an amine with the appropriate ring size followed by a proton transfer reaction leads to the formation of an interlocked rotaxane species.

- Electrooxidative cyclization of hydroquinolyl alcohols, hydroquinolylamines, and dimethyl aminomalonates
-
Several hydroquinolyl alcohols and amines were electrochemically oxidized in methanol in the presence of sodium methoxide and potassium iodide to afford the corresponding intramolecular cyclization products. Furthermore, several amino malonates were electrochemically oxidized to yield the corresponding heterocyclic compounds through an intramolecular carbon-carbon bond formation in the presence of sodium cyanide in methanol. CSIRO 2007.
