Abstract

Provided are processes of preparing glycolurils and cucurbiturils using the glycolurils by microwave irradiation. Therefore, condensation and cyclization reactions for preparation of industrially widely applied cucurbituril derivatives, oxidation reaction for preparation of hydroxycucurbiturils, and condensation and cyclization reactions between glycolurils and paraformaldehyde or a formaldehyde solution can be efficiently performed in a short time.
