摘要

The enantioselective construction of quaternary stereogenic carbon centers is a challenge in organic synthesis. Much progress has been made with enantioselective catalytic methods, but still no general solution to this synthetic problem exists.[1] A reliable alternative strategy for the predictable installation of a quaternary stereocenter is 1, 3-chirality transfer from a more readily accessible stereogenic center by a sigmatropic process, such as the Claisen ...
