The title compound, C 18 H 28 N 6 O 6 , is a derivative of glycoluril, with two ethyl acetate substituents on the convex face of the glycoluril system. Two equivalent six-membered rings bind the N atoms from separate rings of the glycoluril unit to form the flexible sidewalls of a molecular clip. On

In the title compound, C 28 H 32 N 6 O 6 , the dihedral angles between the two fused five-membered rings in the glycoluril unit and between the two terminal benzene rings are 71.78 (2) and 66.76 (2) , respectively. The molecules are connected mainly by van der Waals forces.
The crystal structure of the title benzofuran derivative, C~16~H~23~NO~3~, has been elucidated. The tricyclic core, __i.e.__ the tetrahydrobenzo–dihydrofuro–pyrrolidine ring system, is non-planar owing to the folding of the five-membered rings at their __cis__ junction. The cyclohexene ring assumes
The molecule of the title compound, C 22 H 36 N 6 O 6 , exhibits normal geometric parameters. Both imidazole rings adopt envelope conformations with the C O group at the flap position. The triazinane rings adopt chair conformations.
