Abstract
The development of a one-step catalytic method for the enantioselective construction of contiguous tertiary and allcarbon quaternary centers is a challenging task but of great significance.[1, 2] Among the limited number of available approaches for the assembly of such sterically congested structures by a single transformation, the Claisen rearrangement, well-known as one of the most effective carbonÀ carbon bond-formation strategies, has ...
