Palladium-catalyzed allylic amination using aqueous ammonia for the preparation of primary amines has been realized. It is noteworthy that the use of aqueous ammonia is essential and that ammonia gas did not react at all. The first catalytic asymmetric synthesis using aqueous ammonia as a nitrogen source has also been demonstrated.

cyclopropylimines and substituted alkenes to generate aminocyclopentane derivatives. The Schiff base of the cyclopropylimine was designed to enable a masked N-centered radical approach in which the requisite open-shell character was achieved upon excitation with visible light. The cycloaddition products were directly converted to N-functionalized aminocyclopentanes via solvolysis and N-acylation. The photochemical
