The diethylzinc-promoted reaction of dehydroamino acid derivative with electrophilic π-allylpalladium complex proceeded smoothly to afford α,α-disubstituted amino acids via a tandem radical and anionic carbon-carbon bondforming processes.

all-substituted sp3-hybridized carbon-center was investigated via tandem reaction of dehydroamino acid derivatives. The diethylzinc-promoted reaction of dehydroamino acid derivatives with acid anhydride or π-allylpalladium complex proceeded smoothly to afford α,α-disubstituted amino acids via a radical and anionic carbon–carbon bond-forming processes.
