Enantioselective synthesis of γ-silylated amino acids is reported, using a four-step procedure based on the silylcupration of ethynyloxazolidine 2. Silylcuprates 6a-c are highlighted as useful reagents to be employed with enantiomerically enriched substrates. Vinylsilanes 5 are easily prepared and highlighted as useful intermediates to yield the final compounds after reduction, opening of the oxazolidine ring, and oxidation. Moreover, β,γ- unsaturated amino acids are obtained as very interesting vinylglycine derivatives. The capability of silicon-containing amino acids to be incorporated into dipeptides is also shown.
