Abstract:

A novel nitrogen-centered radical-induced 1,2-carbon migration reaction of allylic alcohols has been developed. This method provides easy access to a variety of α-quaternary-β-amino ketones under mild reaction conditions. The reaction has a wide substrate scope and operational simplicity. Mechanistic studies suggest that 1,2-carbon migration is induced by regioselective nitrogen-centered radical addition to the alkene unit.
