Despite the long history of [2,3]-sigmatropic
rearrangements, there are surprisingly few catalytic and enantioselective
variants of these transformations. This article describes the most common
strategies developed for stereoselective [2,3]-rearrangements
of amine N-oxides (Meisenheimer rearrangement),
including our recently reported palladium-catalyzed enantioselective
process.
