Process for the preparation of nitrogenous polyheterocycles catalyzed byniron compounds |
| abstract |
Process for the preparation of nitrogenous polyheterocycles catalyzed by iron compounds. # The invention describes a new process for the preparation of nitrogenous polyheterocycles of formula (I), by tandem coupling / double heterocyclation reaction of an ortho-functionalized amine of formula (II ) and an alkynoic acid of formula (III) catalyzed by an iron compound, 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 an aprotic polar solvent, and optionally in the presence of a pyridine derivative. |
