Abstract
Our recent works concerning asymmetric synthesis via chiral π-allyl transition metal complexes are reviewed; focussed on inter- and intramolecular asymmetric palladium-catalyzed allylations of chiral enamines, imines, and hydrazones bearing allyl esters or phosphine groups, and intramolecular asymmetric metallo-ene reactions. A novel and excellent method for asymmetric α-allylation of carbonyl compounds via their chiral enamines and imines bearing allyl esters has been developed. Readily available chiral allyl esters, (S) -proline and (S) -valine allyl ester, have been found to serve as good asymmetric allylating reagents in the palladium-catalyzed reactions of the chiral enamines and imines derived from them.
