Abstract
Efficient syntheses of saturated nitrogenated heterocycles can be accomplished within the conceptually unique approach of the intramolecular diamination of alkenes. These unprecedented reactions give rise to vicinal diamine-derived heterocycles, in which the two amino groups are linked within a spacer unit. Alternatively, the reaction can be initiated by intramolecular alkene amination followed by the addition of a second nitrogen source in an intermolecular manner. These approaches furnish pyrrolidines and piperidines as the heterocyclic units. The reactions are catalyzed by a number of transition metal–based oxidation catalysts, which are of conceptually high importance. This chapter provides an overview of the accomplishments in homogeneously catalyzed alkene diamination for the preparation of diamine-derived heterocycles.
