—— | 3a,6a-bis(4-methoxyphenyl)-tetrahydroimidazo[4,5-d]imidazole-2,5-(1H,3H)-dione | 663908-73-4 | C18H18N4O4 | 354.365 |
Several new ditopic receptors have been synthesized from 4,4′-bis(methoxyphenyl)glycoluril (1). The first receptor site is a cleft composed of two fused 2-imidazolone rings, which are flanked by two aromatic side walls, and the second site is a crown ether moiety.Key words: receptors, crown compounds, glycoluril, molecular clips.
