title: Samarium diiodide-induced intramolecular pinacol coupling of dinitrones: synthesis of cyclic cis-vicinal diamines.
abstract: Pinacol coupling of alkyl dinitrones mediated by SmI2 was achieved in the presence of a proton source allowing the synthesis of cyclic vicinal diamines with good cis-selectivity.
