The catalysed enantioselective formation of carbon-nitrogen bonds by the hydroamination reaction is reviewed. All examples deal with substrates containing non-activated carbon-carbon multiple bonds which are transformed either via intramolecular or intermolecular reactions. Structurally different complexes already provided nitrogen containing compounds/heterocycles
