Enantioselective 6π Electrocyclizations: Pushing the Limits in Organocatalytic Pericyclic Reactions

摘要

Pericyclic reactions, which include cycloaddition reactions, sigmatropic rearrangements and electrocyclizations, represent one of the most important types of transformations in synthetic organic chemistry. Whereas a large number of methods are nowadays known for carrying out cycloaddition reactions using asymmetric catalysis and the number of reports dealing with catalytic enantioselective sigmatropic rearrangements is rapidly growing, electrocyclizations have remained as a rather unexplored field of research.
