Glycoluril can be used to make Cucurbiturils. Cucurbiturils are macrocyclic molecules made of glycoluril (=C4H2N4O2=) monomers linked by methylene bridges. They have been used by chemists for various applications, including drug delivery, asymmetric synthesis, molecular switching, and dye tuning."}]
