Unsymmetrical tetrasubstituted ureas from tertiary carbamoylimidazole: activation by AlMe3?
Organic & Biomolecular Chemistry Pub Date: 2012-06-13 DOI: 10.1039/C2OB25412C
Abstract
An efficient and general method for the synthesis of unsymmetrical tetrasubstituted ureas from carbamoylimidazole is described. The conversion is achieved by the concurrent quarternization of the imidazole nitrogen and activation of amines with AlMe3.
