The γ and δ-keto α-amino acid derivatives 1a and 1b were prepared from L-aspartic and L-glutamic acid respectively via alkylation of the corresponding β-ketoesters 3a and 3b followed by subsequent ester cleavage and decarboxylation.

activated zinc gives the corresponding alkylzinc iodide 14, which reacts under palladium catalysis with a range of electrophiles (aryl iodides and acid chlorides) to give the corresponding adducts 19 and 22. While the reactions with aryl iodides provide acceptable yields in THF as solvent, the corresponding reactions with acid chlorides requires dimethoxyethane or, preferably, a combination of toluene
