Methodology has been established for the formation of
enantiomerically enriched α-amino acids using palladium-catalysed
allylic amination. The formation of enantiomerically enriched
allylamines has been achieved with high enantioselectivity. Oxidative
cleavage of the allylamines provides arylglycine and glutamic acid
derivatives. Additionally, enantiomerically enriched β-amino acids
have been prepared in high enantiomeric excess. Palladium-catalysed
asymmetric allylic substitution is used as the key synthetic
transformation.
