Abstract

Stereochemistry of intramolecular palladium-catalyzed asymmetric allylations of chiral enamines involving allylating species in the molecules is discussed, compared with that of intermolecular reactions. The mechanistic pathway for this asymmetric induction is proposed on the basis of the stereochemical results.
