Designer cyclopalladated-amine catalysts for the asymmetric Claisen rearrangement

Abstract

The novel ortho-metallated complex (R,R)-di-µ-chlorobis{9-[(1-dimethylamino)ethyl]-10-phenanthrenyl-C,N}dipalladium has been prepared and found to be a significantly better catalyst than its phenyl and naphthylamine analogues for the asymmetric Claisen rearrangement of a non-activated allyl imidate.
