A Cyclophane Receptor for the Selective Complexation of Adenine Derivatives in Water
摘要:
A water-soluble oxacyclophane based upon p-xylylenebis[4-hydroxy-3-carboxybenez] and p-xylene units tethered trough an aliphatic chain has been synthesized. The receptor binds selectively to neutral adenine derivatives forming an intracavity 1:1 complex. The interaction energies for the complexes range from 7 to 13 kJ mol(-1) in alkaline D2O. The geometry of the complex between 1(dicarboxylate) and 9-ethyladenine has been mapped out through NMR studies and is also supported by molecular modeling and theoretical AM1 calculations.
