To obtain enantiomerically pure products without using stoichiometric quantities of chiral components is now possible for the title reactions [Eq. (a)]. Chiral Lewis acids M′X n are employed, which enable an excellent facial differentiation. In some cases these catalysts provide enantiomeric excesses greater than 95% and outstanding chemical yields.
