Synthesis, Crystal Structure of the Receptor Derived from Diethoxycarbonyl Glycoluril for Aromatic Amide Guest

The receptor derived from the diethoxycarbonyl glycoluril was synthesized and characterized by IR, 1H NMR, MS techniques and X‐ray single crystal analysis. Single crystal X‐ray diffraction reveals that the receptor remains monomeric because of its bulky t‐Bu groups on the side walls. Its unique binding properties for aromatic amides were studied through 1H NMR and IR techniques.
