Abstract

The Overman rearrangement is an important method for the construction of allylic amine derivatives from allylic imidates and has found widespread application in organic synthesis.[1] Since the first enantioselective version of this PdII-catalyzed aza-Claisen-type rearrangement appeared in 1997,[2] significant progress has been marked by the introduction of the oxazoline-based palladacycle catalysts COP-X [3] and FOPX [4]( ...
