The synthesis of a series of γ,δ-unsaturated N-protected α-amino acid methyl esters from the coupling of different allylsilanes and glycidyl cation equivalents 6 and 7 is described. Reactions with methoxyglycine derivative 6 are induced with BF3·OEt2; in the case of chloroglycine derivative 7 SnCl4 is used as Lewis acid. Reactions are fully regioselective, but show low stereoselectivity. The conversion
