چکیده

The title compound, C(15)H(22)N(2)O(3), has been isolated as a by-product of an oxidative cleavage of the C-C bond linking two five-membered rings of 1,3-dicyclo-hexyl-5-(3-oxo-2,3-dihydro-benzofuran-2-yl)imidazolidine-2,4-dione. Individual mol-ecular units are engaged in weak C=O⋯C=O inter-actions [O⋯C = 2.814 (10) and 2.871 (11) Å], leading to the formation of supra-molecular chains which close pack, mediated by van der Waals contacts, in the bc plane.

1,3-Dicyclo­hexyl­imidazolidine-2,4,5-trione: a second polymorph

The title compound, C(15)H(22)N(2)O(3), was obtained as a by-product of oxidative cleavage of 1,3-dicyclo-hexyl-(3-oxo-2,3-dihydro-benzofuran-2-yl)imidazolidine-2,4-dione. Herein, we report the crystal structure of a second polymorph, which was obtained by crystallization from an ethanol solution at 253 K, instead of slow evaporation of the same solvent at room temperature. While the first poly...

1,3-substituted imidazolidine-2,4,5-triones: synthesis and inhibition of cholinergic enzymes.

A series of novel and highly active acetylcholinesterase and butyrylcholinesterase inhibitors derived from substituted benzothiazoles containing an imidazolidine-2,4,5-trione moiety were synthesized and characterized. The molecular structure of 1-(2,6-diisopropyl-phenyl)-3-[(1R)-1-(6-fluoro-1,3-benzothiazol-2-yl)ethyl]-imidazolidine-2,4,5-trione (3g) was determined by single-crystal X-ray diffr...
