This paper describes an enantioselective intermolecular allylicaminationcatalyzed by a chiral Brønsted acid via a possible chiral contact ion pair intermediate. A variety of symmetrical or unsymmetrical allylic alcohols can be smoothly aminated to afford the desired products in moderate to high yields with good enantioselectivities and/or regioselectivities.

Cathepsins, intracellular proteases, are known to be involved in a number of physiological processes such as degradation of extracellular proteins, prohormone processing, progressions of atherosclerosis etc.
