Application of 16004-15-2. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 1-(Bromomethyl)-4-iodobenzene, is researched, Molecular C7H6BrI, CAS is 16004-15-2, about Cu-catalyzed N-3-Arylation of Hydantoins Using Diaryliodonium Salts. Author is Neerbye Berntsen, Linn; Nova, Ainara; Wragg, David S.; Sandtorv, Alexander H..
A general Cu-catalyzed, regioselective method for the N-3-arylation of hydantoins I (R = R1 = H, Me, Ph; R2 = H, Me), (R)-5-methylhydantoin and (S)-Tetrahydro-1H-pyrrolo[1,2-c]imidazole-1,3(2H)-dione is described. The protocol utilizes aryl(trimethoxyphenyl)iodonium tosylate [2,4,6-(OCH3)3C6H2IR3]+[4-CH3C6H4SO3]- (R3 = Ph, 2-fluorophenyl, 2,3-dihydro-1-benzofuran-5-yl, etc.) as the arylating agent in the presence of triethylamine and a catalytic amount of a simple Cu-salt. The method is compatible with structurally diverse hydantoins I and operates well with neutral aryl groups or aryl groups bearing weakly donating/withdrawing elements. It is also applicable for the rapid diversification of pharmaceutically relevant hydantoins II [Ar = Ph, 4-(methoxycarbonyl)benzen-1-yl, 4-[(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)methyl]benzen-1-yl] and III.
