Oxidative cyclization of acyclic ureas with bis(trifluoroacetoxy)iodobenzene to generate N-substituted 2-benzimidazolinones
Romero, Arthur G.,Darlington, William H.,Jacobsen, E. Jon,Mickelson, John W.
, p. 2361 - 2364 (1996)
A facile method to synthesize N-substituted 2-benzimidazolinones from secondary aromatic amines is presented. Sequential treatment of a secondary aromatic amine with phosgene and methoxylamine afforded an acyclic 3-substituted 3-aryl-1-methoxy urea. Brief
Synthetic method of benzimidazolone skeleton
-
Paragraph 0030; 0031, (2021/11/19)
The invention discloses a synthetic method of a benzimidazolone skeleton, and belongs to the technical field of organic chemistry. The synthesis method uses phenylurea and derivatives thereof as reactants. When the aryl iodide is used as a catalyst, m-chl
APPROACH TO THE 1-METHOXY-2-BENZIMIDAZOLINONES
Perronnet, Jacques,Demoute, Jean-Pierre
, p. 507 - 512 (2007/10/02)
With t-butyl hypochlorite the 1-methoxy-3-arylureas are easily converted into the unstable corresponding 1-chloro-1-methoxy-3-arylureas.Cyclization of the latter under basic conditions gives the 1-methoxy-2-benzimidazolinones.The two steps can be carried
