description Procedure for the preparation of nitrogen-containing polyheterocycles catalyzed by iron compounds. The invention describes a new process for the preparation of nitrogen-containing polyheterocycles of formula (I), by coupling tandem reaction/double heterocyclisation of an ortho-functionalized amine of formula (II) and an alkynoic acid of formula (III) catalyzed by a compound of iron, such as fe (0), a salt or a complex of fe (II) or fe (III), in the absence of solvent or using an apolar solvent or a polar aprotic solvent, and optionally in the presence of a pyridine derivative . (Machine-translation by Google Translate, not legally binding) Procedimiento para la preparación de poliheterociclos nitrogenados catalizado por compuestos de hierro. La invención describe un nuevo procedimiento para la preparación de poliheterociclos nitrogenados de fórmula (I), por reacción tándem de acoplamiento/doble heterociclación de una amina orto-funcionalizada de fórmula (II) y un ácido alquinoico de fórmula (III) catalizada por un compuesto de hierro, tal como Fe (0), una sal o un complejo de Fe(II) o Fe(III), en ausencia de disolvente o empleando un disolvente apolar o un disolvente polar aprótico, y opcionalmente en presencia de un derivado de piridina.
