Enantioselective palladium catalyzed allylic substitution with chiral thioether derivatives of ferrocenyl-oxazoline and the role of planar chirality in this reaction
Abstract
A series of chiral thioether dervatives of ferrocenyl-oxazolines, prepared with diastereoselectivities >95:5, have been shown to be highly efficient catalysts for a palladium catalyzed allylic substitution reaction, with enantioselectivity of 81–98% ee, and the role of planar chirality in these ligands was also discussed.
