we report the regio- and chemoselectivereactions of indole with carbamoylelectrophiles in presence of AlMe3. Indole-3-carboxamide was prepared in one-step from a reaction of indole with tertiary carbamoylimidazole in the presence AlMe3. Under conditions for the formation of an aluminium ate complex, the reaction was diverted to the indole nitrogen. Secondary carbamoylelectrophiles in the presence

An efficient and general method for the synthesis of unsymmetricaltetrasubstitutedureas from carbamoylimidazole is described. The conversion is achieved by the concurrent quarternization of the imidazole nitrogen and activation of amines with AlMe3.
