Graphical Abstract
An atom-economical method has been developed for the preparation of chiral vicinal diamines through a dynamic kinetic asymmetric allylic amination and acyl-group migration of vinyl aziridines with imido carboxylates. Application of the asymmetric transformation enabled the concise synthesis of the azepane core 1 of (+)-balanol and its syn analogue.
