Saturated nitrogen heterocycles are essential pharmacophores in drugs and natural products, and general methods for their enantioselective synthesis are still highly sought after. A new direct approach utilizing hemiaminal methyl ethers as N-acyliminium precursors for the enantioselective preparation of cyclic, aliphatic and 2-subsituted pyrrolidines, piperidines and azepanes has been achieved.
