Abstract: Herein, a nickel-catalyzed α-alkenylation reaction of asymmetric cyclic ketones at the sterically hindered α-position with alkenes is disclosed. The high regioselectivity might originate from the acid-catalyzed enolization reaction, selectively generating the thermodynamically favored enol. The… read more here.
