Synthesis and separation of cucurbit[n]urils and their derivatives

“…Glycolurils incorporating substituents on their nitrogen atoms have proved useful for the synthesis of both acyclic 122 and cyclic 123 Q[n] analogs as well as for other purposes. 78,79,[124][125][126] Isaacs and co-workers employed the glycoluril diethyl ester shown in Fig. 12 as a starting material for the synthesis of a series of N-substituted glycolurils (Fig.…”
