Patent

CA 2412782

The invention concerns a method for preparing cyclic urea compounds from at least an activated carbamic acid derivative containing an unprotected primary or secondary amine function, comprising a cyclization step which consists in a reaction between the primary or secondary amine function and the carbamic acid function of said carbamic acid derivative(s).

La présente invention a pour objet un procédé de préparation de composés urées cycliques à partir d'au moins un dérivé activé d'acide carbamique contenant une fonction amine primaire ou secondaire non protégée, comprenant une étape de cyclisation par réaction entre la fonction amine primaire ou secondaire et la fonction acide carbamique dudit ou desdits dérivés d'acide carbamique.
