Abstract: The reactions of 1-alkyl-5-hydroxy-4,5-diphenyl-1,5-di-hydro-2H-imidazol-2-ones or 7-hydroxy-7,7a-diphenyltetrahydroimidazo[5,1-b][1,3]oxazol-5(6H)-one with 1-phenylurea selectively afford new 1-substituted 3a,6,6a-triphenylglycolurils. Crystals of four representatives were studied by X-ray diffraction when the formation of two conglomerates was discovered.

Keywords: glycolurils, 1-alkylimidazolones, tetrahydroimidazo[5,1-b][1,3]oxazol-5(6H)-one, 1-phenylurea, supramolecular organization, regioselective condensation, X-ray.
