Iron-Catalyzed Intra-intermolecular Aminoazidation of Alkenes

Autor: Farouk Berhal, Sandra Abi Fayssal, Alessandro Giungi, Guillaume Prestat

Publikováno v: Organic Process Research & Development. 24:695-703

An intra-intermolecular iron-catalyzed aminoazidation of non-activated alkenes is reported for the preparation of imidazolidinone, oxazolidinone, and pyrrolidinone derivatives. The method uses chea...
