original discovery, catalyzed enantioselective variants of the venerable Claisenrearrangement remain relatively rare. We have discovered a cooperative transition metal-Lewis acid cocatalyst system that affects highly enantio- and diastereoselective examples of archetypical Claisenrearrangements. The catalyzed rearrangements proceed using an easily prepared enantioenriched transition metal catalyst
